The Semigroup Property of Value Functions in Lagrange Problems

A characterization of triple semigroup of ternary functions and Demorgan triple semigroup of ternary functions

Loops and the Lagrange Property

Let F be a family of finite loops closed under subloops and factor loops. Then every loop in F has the strong Lagrange property if and only if every simple loop in F has the weak Lagrange property. We exhibit several such families, and indicate how the Lagrange property enters into the problem of existence of finite simple loops. The two most important open problems in loop theory, namely the e...

new semigroup compactifications via the enveloping semigroups of associated flows

this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.

A Semigroup Approach to Stochastic Dynamical Boundary Value Problems

In many physical applications, the evolution of the system is endowed with dynamical boundary conditions, i.e., with boundary operators containing time derivatives. In this paper we discuss a generalization of such systems, where stochastic perturbations affect the way the system evolves in the interior of the domain as well as on the boundary. keywords: Stochastic differential equations, bound...
