Results 81 to 90 of about 69,892 (204)
Journal of Algebra, 2003 This paper continues the investigation of \(RC\)-semigroups introduced by the authors [in Semigroup Forum 62, No. 2, 279-310 (2001; Zbl 0982.20051)]. ``Spiritually'', this paper is close to previous investigations of \textit{B. Schweizer} and \textit{A. Sklar} [e.g., Bull. Am. Math. Soc. 73, 510-515 (1967; Zbl 0217.01703)]. ``Agreeable semigroups'' are

Fuzzy semigroups via semigroups
, 2023 The theory of fuzzy semigroups is a branch of mathematics that arose in early 90's as an effort to characterize properties of semigroups by the properties of their fuzzy subsystems which include, fuzzy subsemigroups and their alike, fuzzy one (resp. two) sided ideals, fuzzy quasi-ideals, fuzzy bi-ideals etc.

Equivariant toric geometry and Euler–Maclaurin formulae
Communications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 451-557, March 2026.Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Semiclassical inequalities for Dirichlet and Neumann Laplacians on convex domains
Communications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 762-822, March 2026.Abstract We are interested in inequalities that bound the Riesz means of the eigenvalues of the Dirichlet and Neumann Laplacians in terms of their semiclassical counterpart. We show that the classical inequalities of Berezin–Li–Yau and Kröger, valid for Riesz exponents γ≥1$\gamma \ge 1$, extend to certain values γ<1$\gamma <1$, provided the underlying ...

Semigroup compactifications by generalized distal functions and a fixed point theorem
International Journal of Mathematics and Mathematical Sciences, 1991 The notion of Semigroup compactification which is in a sense, a generalization of the classical Bohr (almost periodic) compactification of the usual additive reals R, has been studied by J. F. Berglund et. al. [2].

Journal of Algebra, 2000 For a finite-dimensional algebra \(A\) over an infinite field \(K\), the subspace semigroup \({\mathcal S}(A)\) consists of all subspaces of \(A\) with operation \(V*W=\text{lin}_KVW\), the linear span of \(VW\) over \(K\). The authors describe the structure of \({\mathcal S}(A)\), showing in particular that, similar to any linear algebraic semigroup, \

Brownian Motion With Partial Resetting Conditioned to Stay Positive
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract We consider Brownian motion with partial resetting, which has recently attracted a lot of attention in physics as well as the mathematics literature. We analyze the speed of convergence of this process towards stationarity as well as its quasistationary behavior.

Planarity ranks for varieties of equationally noetherian semigroups [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. ИнформатикаThe problem of describing semigroup varieties with finite planarity rank is researched. In addition to the previously obtained results the author finds new countable infinite series of semigroup varieties with finite planarity rank.

International Journal of Mathematics and Mathematical Sciences, 2001 We consider the semigroup S¯ of the fuzzy points of a semigroup S, and discuss the relation between the fuzzy interior ideals and the subsets of S¯ in an (intra-regular) semigroup S.

, 1997 This chapter gives an overview on what is often called the algebraic theory of finite automata. It deals with languages, automata and semigroups, and has connections with model theory in logic, boolean circuits, symbolic dynamics and topology.
