Short-term solar eclipse predictions using Euclidean geometry and dynamical systems
Alin-Doru Aluas, Valerian-Alin Fodor, Virgilius-Aurelian Minuta
We propose a computationally inexpensive algorithm to determine whether an opaque spherical body eclipses a luminous one, using only classical geometrical tools. We apply this meth…
An algorithm for approximating the metric projection onto a superelliptic disk
Valerian-Alin Fodor, Virgilius-Aurelian Minuta
We study conditions under which the metric projection onto a strictly convex body can be approximated by the projections onto polygonal approximations (in the Hausdorff-Pompeiu sen…
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.
Character triples and equivalences over a group graded G-algebra
Andrei Marcus, Virgilius-Aurelian Minuta
We introduce Morita and Rickard equivalences over a group graded G-algebra between block extensions. A consequence of such equivalences is that Späth's central order relation holds…
Group graded endomorphism algebras and Morita equivalences
Andrei Marcus, Virgilius-Aurelian Minuta
We prove a group graded Morita equivalences version of the "butterfly theorem" on character triples. This gives a method to construct an equivalence between block extensions from a…
