Stacks of cyclic covers of projective spaces
, 2003 We define stacks of uniform cyclic covers of Brauer-Severi schemes, proving that they can be realized as quotient stacks of open subsets of representations, and compute the Picard group for the open substacks parametrizing smooth uniform cyclic covers ...

On covers of cyclic acts over monoids
, 2008 In (Bull. Lond. Math. Soc. 33:385–390, 2001) Bican, Bashir and Enochs finally solved a long standing conjecture in module theory that all modules over a unitary ring have a flat cover.

Categorical Properties of Soft Sets
The Scientific World Journal, 2014 The present study investigates some novel categorical properties of soft sets. By combining categorical theory with soft set theory, a categorical framework of soft set theory is established.

Classes of modules closed under projective covers
Open MathematicsIn this work, we study some classes of modules closed under submodules, quotients, and projective covers, even if the left projective cover of an arbitrary left module not always exists. We obtain a characterization of artinian principal ideal rings when

Constructing Permutation Rational Functions From Isogenies
, 2017 A permutation rational function $f\in \mathbb{F}_q(x)$ is a rational function that induces a bijection on $\mathbb{F}_q$, that is, for all $y\in\mathbb{F}_q$ there exists exactly one $x\in\mathbb{F}_q$ such that $f(x)=y$.

Quasi-Projective Covers and Direct Sums [PDF]
Proceedings of the American Mathematical Society, 1970 In this paper R R denotes an associative ring with an identity, and all modules are unital left R R -modules. It is shown that the existence of a quasi-projective cover for each module implies that each module has a projective cover. By a similar technique the following statements are shown to be equivalent: 1.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Cosets, characters and fusion for admissible-level osp(1|2) minimal models
Nuclear Physics B, 2019 We study the minimal models associated to osp(1|2), otherwise known as the fractional-level Wess–Zumino–Witten models of osp(1|2). Since these minimal models are extensions of the tensor product of certain Virasoro and sl2 minimal models, we can induce ...

Projections of random covering sets [PDF]
Journal of Fractal Geometry, Mathematics of Fractals and Related Topics, 2015 We show that, almost surely, the Hausdor dimension s0 of a random covering set is preserved under all orthogonal projections to linear subspaces with dimension k > s_0 . The result holds for random covering sets with a generating sequence of ball-
