Topological structures in Colombeau algebras: topological   $\widetilde{\C}$-modules and duality theory
  We study modules over the ring $\widetilde{\C}$ of complex generalized numbers from a topological point of view, introducing the notions of $\widetilde{\C}$-linear topology and locally convex $\widetilde{\C}$-linear topology. In this context particular attention is given to completeness, continuity of $\widetilde{\C}$-linear maps and elements of duality theory for topological $\widetilde{\C}$-modules. As main examples we consider various Colombeau algebras of generalized functions
