Pointed Hopf Algebras of Discrete Corepresentation Type
Miodrag Iovanov, Emre Sen, Alexander Sistko +1
We classify pointed Hopf algebras of discrete corepresentation type over an algebraically closed field K with characteristic zero. For such algebras , we explicitly determine th…
On Incidence Algebras and their Representations
Miodrag C. Iovanov, Gerard D. Koffi
We provide a unified approach, via deformations of incidence algebras, to several important types of representations with finiteness conditions, as well as the combinatorial algebr…
Semiperfect and coreflexive coalgebras
Sorin Dascalescu, Miodrag C. Iovanov
We study non-counital coalgebras and their dual non-unital algebras, and introduce the finite dual of a non-unital algebra. We show that a theory that parallels in good part the du…
Frobenius Structural Matrix Algebras
Sorin Dascalescu, Miodrag C. Iovanov, Sorina Predut
We discuss when the incidence coalgebra of a locally finite preordered set is right co-Frobenius. As a consequence, we obtain that a structural matrix algebra over a field is F…
Quiver Algebras, Path Coalgebras and co-reflexivity
S. Dascalescu, M. C. Iovanov, C. Nastasescu
We study the connection between two combinatorial notions associated to a quiver: the quiver algebra and the path coalgebra. We show that the quiver coalgebra can be recovered from…
