An Algorithm for Approximating the Metric Projection onto a Superelliptic Disk
Valerian-Alin Fodor, Virgilius-Aurelian Minuta
We propose a new algorithm for approximating the metric projection onto a superelliptic disk of order , i.e., the convex hull of a superellipse (Lamé curve), and prove its con…
Skew category algebras, twisted tensor product algebras and induction of precosheaves
Tiberiu Coconet, Virgilius-Aurelian Minuta, Constantin-Cosmin Todea
We show that a skew category algebra can be embedded into a twisted tensor product algebra. We investigate the extension of some concepts of Puig and Turull from group algebras to…
An exact sequence for the graded Picent
Andrei Marcus, Virgilius-Aurelian Minuta
To a strongly -graded algebra with -component we associate the group of isomorphism classes of invertible -graded -bimodu…
Blockwise relations between triples, and derived equivalences for wreath products
Andrei Marcus, Virgilius-Aurelian Minuta
Motivated by the reduction techniques involving character triples for the local-global conjectures, we show that a blockwise relation between module triples is a consequence of a d…
Group graded Morita equivalences for wreath products
Virgilius-Aurelian Minuta
Starting with group graded Morita equivalences, we obtain Morita equivalences for tensor products and wreath products.
Graded Morita theory over a G-graded G-acted algebra
Virgilius-Aurelian Minuta
We develop a group graded Morita theory over a G-graded G-acted algebra, where G is a finite group.
