HNN extensions of inverse semigroups with zero
, 2007 We study a construction of an HNN extension for inverse semigroups with zero. We prove a normal form for the elements of the universal group of an inverse semigroup that is categorical at zero, and use it to establish structural results for the universal

HNN extensions of inverse semigroups
, 1996 The concept of HNN extensions of groups was introduced by Higman, Neumann and Neumann in their study of embeddability of groups in 1949. HNN extensions and amalgamated free products have played a crucial role in combinatorial group theory, especially for

Closed Inverse Subsemigroup Lattices of Inverse Semigroups
, 1994 It was of great interest to study the relationships between the structure of a group and the structure of its subgroup lattice. Later in the literature the same topic was considered for the case of inverse semigroups.

Fixed Point Theory and Applications, 2011 In this paper, using strongly monotone and lipschitzian operator, we introduce a general iterative process for finding a common fixed point of a semigroup of nonexpansive mappings, with respect to strongly left regular sequence of means defined on an ...
