A bivariant theory for the Cuntz semigroup [PDF]
We introduce a bivariant version of the Cuntz semigroup as equivalence classes of order zero maps generalizing the ordinary Cuntz semigroup. The theory has many properties formally analogous to KK-theory including a composition product. We establish basic properties, like additivity, stability and continuity, and study categorical aspects in the ...

Neutrosophic Left Almost Semigroup [PDF]
In this paper we extend the theory of neutrosophy to study left almost semigroup shortly LAsemigroup. We generalize the concepts of LA-semigroup to form that for neutrosophic LA-semigroup.

Semigroup theory applied to options
Black and Scholes (1973) proved that under certain assumptions about the market place, the value of a European option, as a function of the current value of the underlying asset and time, verifies a Cauchy problem.

An example in the theory of hypercontractive semigroups [PDF]
Let \(L=xd^ 2/dx^ 2+(1-x)d/dx\) on smooth functions on (0,\(\infty)\) be the Laguerre operator.

Smarandache U-liberal semigroup structure [PDF]
In this paper, Smarandache U-liberal semigroup structure is given. It is shown that a semigroup S is Smarandache U-liberal semigroup if and only if it is a strong semilattice of some rectangular monoids. Consequently, some corresponding results on normal

Let R be a ring. The circle operation is the operation a∘b=a+b−ab, for all a,b∈R. This operation gives rise to a semigroup called the adjoint semigroup or circle semigroup of R. We investigate rings in which the adjoint semigroup is regular. Examples are

₷Ꝗ-Neutrosophic Structures in Semigroup Theory [PDF]
In this paper, we define and study a new fuzzy algebraic structure called ₷Ꝗ-neutrosophic fuzzy semigroups (₷Ꝗ-NFS) as a generalization of fuzzy algebra in the framework of ₷-semigroups.

Representation of right zero semigroups and their semilattices by a transformation semigroup
Background. As is known, an arbitrary semigroup can be represented by a semigroup of transformations that are right shifts either in this semigroup itself or in the extended semigroup obtained from the original one by adding an outer unit. The problems
