(category theory) A morphism which has an inverse; the composition of the morphism and its inverse yields either one of two identity morphisms (depending on the order of composition).
“Furthermore, in the case of Riesz bases we prove that those functions are isomorphisms.”
“Lectures on Duflo isomorphisms in Lie algebra and complex geometry.”
“Moreover, this paper is to derive some straightforward consequences of the relations between quotient SU-algebras and isomorphisms and also investigate some of its properties.”
