Pseudo-Duals of Frames and Modular Riesz Bases in Hilbert $C^\ast$-Modules

In the present article, duals, approximate duals and pseudo-duals (generated by bounded and not necessarily adjointable operators) of a frame in a Hilbert $C^\ast$-module are characterized and some of their properties are obtained. Especially, the ones constructed by multiplication operators are dis...
