Search results in STMA are displayed online in packages of 10
(default) to 50 hits. The default display format is in enhanced
HTML-form, which improve the readability but give no display of
formulas.
Much more comfortable is the possible output with the TeX- or
postscript-viewer. These possibilies suppose that the viewers
are installed on your client.
If you wish more detailed information on the displayed database
fields please go to the Display Fields.
For other topics please go to the DIRECTORY.
A simple form of proximity searching is available for this database,
in the following text fields: BI, TI, SO. A group of consecutive
words may be searched for by selecting "contains the expression".
For other topics please go to the DIRECTORY.
The description of mathematical contents within the records of
STMA database requires the use of a formatting language
which is capable of presenting special characters, formulae and
formatting instructions. The most widely used and best known language
for these purposes is TeX. Therefore TeX is used in the encoding
of the data for STMA. However, a TeX-implementation
on your computer is not a necessary condition for STMA Database
to run.
But if high output quality is asked for, then viewers for DVI, PostScript
or PDF
should be available on the system.
For other topics please go to the DIRECTORY.
The Basic Index is the main tool in the subject search of STMA
Database as a bibliographic text-oriented database.
This index contain all single words of the fields describing the
contents of the document.
The following fields are included in the Basic Index:
In order to avoid ballast in this index, frequently used words
(called stopwords) without intrinsic meaning in a mathematical
subject search have been skipped in the generation of the basic
index.
For other topics please go to the DIRECTORY.
Author names have been implemented in a form common to all STN
databases, i.e. last name, first name, middle name. First and
middle names can or cannot be abbreviated. When searching for
an author's name, it is recommended to use only the first initial.
You will get all forms of the first names, because the system
adds automatically a truncation symbol. Thus, the following forms
of implementation are possible: Examples:
Friedrich Wilhelm Mahle as Mahle
Mahle, F.
Mahle, F. W.
Mahle, Friedrich
Mahle, Friedrich W.
Mahle, Friedrich Wilhelm
and as an Editor (e.g.) Mahle, Friedrich W. (ed.)
The recommended search form is:
Mahle, F
The system will automatically search for
Mahle, F*
Names containing a preposition (von, van), article (le), combination
of article and preposition (du, vander), relationships or attributes
(Fitz, Mac, Jun., III) have the format common to their country
of origin. It is therefore recommended to search for names with
the supplements placed in front of the name and after the name.
Document Database Record
Peter von der Muehl as Muehl, Peter von der
Fritz von Heyden (DE) as Heyden, Fritz von
Fritz Von Heyden (US) as Von Heyden, Fritz
A. De L'Aigle as L'Aigle, A de
C. M. Di Bari as Di Bari, C.M.
Michel Del Pedro as Del Pedro, Michel
L. C. MacLean as MacLean, L.C.
John Fitz Gerald as Fitz Gerald, John
A. Miller jun. as Miller, A.jun.
The publisher is also given in the AU field, and is listed with
the supplement (ed.).
Edited by H. Waadeland as Waadeland, H.(ed.)
Editor Anita K. Jones as Jones, Anita K.(ed.)
Names in kyrillic letters have been transcribed according to the
ISO standard. In some cases this transliteration will differ from
that one on the translated document or in the western journal.
In that case we include the different form of spelling as an author
reference displayed in braces in the author field.
For other topics please go to the DIRECTORY.
The title of the original document is not only contained in the
basic index, but also in a special field TI. This is useful in
those cases in which users want to limit his search to title words.
The title is given in original language. In case of original title not in English there is also given an English translation.
For other topics please go to the DIRECTORY.
The complete English word for each language can be searched.

This field contains a great part of the bibliographic information
and information about meetings.
The source field contains the following searchable data:
- the journal title, volume, and pages
- the title of conference volumes etc.
- title of book series
- the name and the place of the publisher
- conference title and place
- publication year (see also the index PY)
All data are parsed into single words and can be searched as text.
Examples:
Journal volume Source contains the expression : ANN INST FOURIER 45
Books of a publisher Source contains the expression : SPRINGER VERLAG
Document of an ISBN Source contains the expression : ISBN 3 540 53342 7
For other topics please go to the DIRECTORY.
The publication year is always written in 4 digits.
You may specify a period from 1 to 5 years entering the first
and last year of the period. The second box may stay empty if
only one year is specified. No entry is necessary for the whole
period of the database.
For other topics please go to the DIRECTORY.
By means of document type it is possible to separate the main
types of publication: Journal article, book, conference article,
etc.
For other topics please go to the DIRECTORY.
Some Documents in STMA are indexed by codes from the MSC Mathematical subject System,
which is a specific classification for the field mathematics.
The corresponding text is included in the Basic Index.
It is also possible to search for the main fields (higher levels)
of the classification if you use the first digit or the first
two digits.
Examples:
35J10 searches all papers to "Schroedinger operator"
35J* searches all papers to "elliptic equations"
35* searches all papers to "partial differential equations"
For other topics please go to the DIRECTORY.
In all cases where the classification is not specific enough there are added English keywords for a detailed description of the
topics .
The display fields UT is only searchable in the Basic Index.
For other topics please go to the DIRECTORY.
The description of a document by a review should
- contain a description of the mathematical content and eventually
give applications
The preferred language for the reviews is English, but reviews
in French, German or Spanish will also be accepted.
The review text (of those languages) is inverted in the Basic Index (BI).
For other topics please go to the DIRECTORY.
The (right) truncation symbol * is used to retrieve various forms
of your search terms. In the author search the truncation is used
automatically.
Left truncation is not available.
For other topics please go to the DIRECTORY.

Introduction
In this mode, automatic truncation of author names is not available.
The form fields can contain a boolean expression buitl with the following
operators: & (and), ^ (and not), these two operators having equal priority
(highest), | (or) (lower priority).
a | b & c ==> a | (b & c)
The evaluation order may be changed by using parentheses.
Inter-field operators (selected through the form's menus) are evaluated
from left to right without any priority.
The expression:
Field_A * Field_B * Field_C * Field_D
is always evaluated as:
((Field_A * Field_B) * Field_C) * Field_D
"*" being one the operators and, or, and not.
Examples
|
Author : |
Wiles,* |
| or |
Author : |
Taylor,* |
| and |
Title : |
Fermat |
will find items:
-
having in the Author field
Taylor or Wiles
-
having the word Fermat in the title field.
But:
|
Title : |
Fermat |
| and |
Author : |
Wiles,* |
| or |
Author : |
Taylor,* |
will find :
-
items with the word Fermat in the title field and authored by
Wiles
-
plus items authored by Taylor.
The first request may also be entered as follows:
|
Author : |
Wiles,* | Taylor,* |
| and |
Title : |

This mode allows complex boolean queries.
The searchable field names are (lowercase):
Examples
| cc = 58g* & an = 885* |
All about section "58G" in volume 885 |
| cc = 58g* & py = 1996:1998 |
All about section "58G" for years 1996 to 1998 |
| au = (bender,* ^ canfield,*) |
The author is Bender, without Canfield |
| au = (bender,* ^ canfield,*) | au = (canfield,* ^ bender,*) |
The author is Bender or Canfield, but not both |
| au = ((bender,* ^ canfield,*) | (canfield,* ^ bender,*)) |
same query as above |
| au = ((bender,* ^ canfield,*) | (canfield,* ^ bender,*)) &
py >= 1997 |
same query, but the item has been published after 1996 |
| ti = (riemann* & (manifold* | variete*)) |
|
| ti = riemann* & manifold* |
Syntax error. The correct query is: ti = (riemann* & manifold*) |
| ti = riemann* manifold* |
Expression search: will find "riemannian manifold", "riemannian manifolds",
etc... |
| bi = (bose einstein | einstein bose) |
... |
| ti = (fermi dirac ^ bose einstein) |
