Stat. 39, No. 3, 411-415 (2010). 2010 Hacettepe University, Faculty of Science, Ankara EN numerical semigroups Ap\'ery sets principal ideals gaps Frobenius numbers Summary: We give some results on principal ideals of a numerical semigroup $S=\langle s_1,s_2,\dots,s_p\rangle$ for $p\ge 2$, $p\in\bbfN$. We also describe some relations between Ap\'ery subsets and ideals of $S$.
