PROFINITE METHODS IN SEMIGROUP THEORY

International Journal of Algebra and Computation, 2002
Many recent results in finite semigroup theory make use of profinite methods, that is, they rely on the study of certain infinite, compact semigroups which arise as projective limits of finite semigroups. These ideas were introduced in semigroup theory in the 1980s, first to describe pseudovarieties in terms of so-called pseudo-identities: this is ...

Towards a Semigroup Pricing Theory

The Journal of Finance, 1985
ABSTRACTIn an arbitrage‐free economy, there will always exist a set of linear operators which map future contingent dividends of securities into their current prices. It happens that such operators will also form an “evolution semigroup” as a consequence of intertemporal analysis of the no‐arbitrage restriction.

Theory of Semigroups

2004
This chapter is devoted to the general theory of semigroups. These topics form the necessary background for the proof of Theorems 1.2 and 1.3. In Sects. 4.1–4.3 we study Banach space valued functions, operator valued functions and exponential functions, generalizing the numerical case.

THE HOMOTOPY THEORY OF INVERSE SEMIGROUPS

International Journal of Algebra and Computation, 2002
We show that abstract homotopy theory can be used to define a suitable notion of homotopy equivalence for inverse semigroups. As an application of our theory, we prove a theorem for inverse semigroup homomorphisms which is the exact counterpart of the well-known result in topology which states that every continuous function can be factorized into a ...

Technique of semigroup ring theory: Regular semigroup rings

Journal of Mathematical Sciences, 1999
Let \(S\) be a semigroup and \(G\) a subgroup of \(S\). Let \(R\) be a ring (perhaps, without unity) and \(R'\) a subring of \(R\). The author gives connections between properties of the group ring \(RG\) and the semigroup ring \(RS\), and also the semigroup rings \(RS\) and \(R'S\).
