Quiver algebras, path coalgebras and coreflexivity
S Dăscălescu, M Iovanov, C Năstăsescu - Pacific journal of mathematics, 2013 - msp.org
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 …

Triangular matrix coalgebras and applications
MC Iovanov - Linear and Multilinear Algebra, 2015 - Taylor & Francis
We formally introduce and study generalized comatrix coalgebras and upper triangular
comatrix coalgebras, which are not only a dualization but also an extension of classical …

[HTML][HTML] Infinite dimensional serial algebras and their representations
MC Iovanov - Journal of Algebra, 2018 - Elsevier
We study arbitrary algebras all of whose indecomposable finite dimensional representations
are uniserial, or more generally, comodules over serial coalgebras. We show that the infinite …

Ó Cortadellas, JL Peña… - Journal of the London …, 2010 - academic.oup.com
We introduce the notion of quantum duplicates of an (associative, unital) algebra, motivated
by the problem of constructing toy-models for quantizations of certain configuration spaces …

[PDF][PDF] Serial categories, quantum groups and the pure semisimplicity conjecture
M Iovanov - Preprint-posted online by author - homepage.divms.uiowa.edu
We consider the pure semisimplicity conjecture in the infinite dimensional case: if in the
category A-lf of locally finite left A-modules over an algebra A every object decomposes as a …

(*)-Serial coalgebras
H Yao, W Fan, Y Ping - Frontiers of Mathematics in China, 2012 - Springer
In this paper, we introduce the notion of (*)-serial coalgebras which is a generalization of
serial coalgebras. We investigate the properties of (*)-serial coalgebras and their …

On the bijectivity of the antipode and serial quantum groups
MC Iovanov - Categorical, Homological and Combinatorial …, 2020 - books.google.com
We give a new criterion for the bijectivity of the antipode of a Hopf algebra in terms of the
tensor category of its co-representations. We apply this to prove the bijectivity of the antipode …

Valued Gabriel quiver of a wedge product and semiprime coalgebras
G Navarro - Frontiers of Mathematics in China, 2013 - Springer
We describe the valued Gabriel quiver of a wedge product of coalgebras and study the
category of comodules of a semiprime coalgebra. In particular, we prove that any monomial …
