An Invitation to Combinatorial Inverse Semigroup Theory [PDF]

open access: yes
Combinatorial inverse semigroup theory is the study of free inverse monoids, their closed inverse submonoids, and their homomorphic images, given in terms of presentations of inverse monoids by generators and relations.

The Semigroup and the Inverse of the Laplacian on the Heisenberg Group

open access: yesCubo, 2010
By decomposing the Laplacian on the Heisenberg group into a family of parametrized partial differential operators Lt ,t ∈ R {0}, and using parametrized Fourier-Wigner transforms, we give formulas and estimates for the strongly continuous one ...

Free Inverse Semigroup

open access: yes
V polgrupi vpeljemo posplošeno definicijo inverza. Polgrupo, v kateri ima vsak element natanko en inverz, imenujemo inverzna polgrupa. Na njej definiramo naravno delno urejenost in vpeljemo pojem kongruenc.
