Malešević, Branko; Todorić, Dragana; Jovović, Ivana; Telebaković, Sonja Formulae of partial reduction for linear systems of first order operator equations. (English) Zbl 1197.15004 Appl. Math. Lett. 23, No. 11, 1367-1371 (2010). Summary: This paper deals with the reduction of non-homogeneous linear systems of first order operator equations with constant coefficients. An equivalent reduced system, consisting of higher order linear operator equations having only one variable and first order linear operator equations in two variables, is obtained by using the rational canonical form.
