If A is a fixed abelian group with endomorphism ring E, then for any group G, Ž . Ž . let G\* s Hom G, A and for any E-module M, let M\* s Hom M, A . The E evaluation map : G ª G\*\* is defined in the usual way and G is A-reflexive if G is an isomorphism. This is strongly related to the question of

We define and study Parikh slender languages and power series. A language is Parikh slender if the number of words in the language with the same Parikh vector is bounded from above. As an application we get a new method for ambiguity proofs of context-free languages and a new proof of an earlier res
Regular perturbation expansions are used to analyse the fluid dynamics of unsteady, inviscid, slender, thin, incompressible (constant density), axisymmetric, upward and downward, annular liquid jets subjected to nonhomogeneous, conservative body forces when both the annular jets are very thin and th
