(Ne)dovršena priča o stilu F. M. Dostojevskog / The (un)finished story of F. M. Dostoevsky’s style

Krasner $F^{(m, n)}$-Hyperrings

$!!!!$ In this paper, the notion of fuzzy $!$ Krasner $!(m, n)$-hyperrings($!F^{(m, n)}!$-hyperrings) by using the notion of$F^m$-hyperoperations and $F^n$-operations is introduced and somerelated properties are investigated. In this regards,relationships between Krasner $F^{(m, n)}$-hyperrings and Krasner$(m, n)$-hyperrings are considered. We shall prove that everyKrasner $F^{(m, n)}$-hyperrin...

M/F theory orbifolds

We consider M-theory on (T ×R)/Zn with M5 branes wrapped on R2. One can probe this background with M5 branes wrapped on T2. The theories on the probes provide many new examples of N = 2 field theories without Lagrangian description. All these theories have Coulomb branches, and we find the corresponding SeibergWitten curves. The exact solution is encoded in a Hitchin system on an orbifolded tor...

In group theory, it is a fundamental question to determine what information about a group is necessary and sufficient tomake a group finitely presented. In this paper, we develop the theory of Σ-invariants due to Robert Bieri and Ralph Strebel [Bieri] whi provides an answer to this question for the class of metabelian groups. We begin our study of Σ-invariants with a digression on group extens...
