Semigroups of Partial Isometries

open access: yes, 2013
We study self-adjoint semigroups of partial isometries on a Hilbert space. These semigroups coincide precisely with faithful representations of abstract inverse semigroups.

Sundual characterizations of the translation group of R [PDF]

An iterative algorithm by viscosity approximation method for mixed equilibrium problems, variational inclusion and fixed point of an infinite family of pseudo-contractive mappings

open access: yes, 2011
The purpose of this paper is to investigate the problem of finding a common element of the set of solutions for mixed equilibrium problems, the set of solutions of the variational inclusion problems for inverse strongly monotone mappings and the set of ...

Resolvent positive operator and two-parameter abstract Cauchy problem

open access: yes, 2007
We use the semigroup theory to study the homogeneous two-parameter abstract Cauchy problem 2-RACP ⎧⎨ ⎩ ∂ ∂ti u(t1, t2) = Hiu(t1, t2) i = 1, 2 ti ∈ [0 , ai] u(0, 0) = u0, u0 ∈ E.

$L^\infty$-uniqueness of Schr\"odinger operators restricted in an open domain

open access: yes, 2008
Consider the Schr\"odinger operator ${\cal A}=-\frac{\Delta}{2}+V$ acting on space $C_0^\infty(D)$, where $D$ is an open domain in $\R^d$. The main purpose of this paper is to present the $L^\infty(D,dx)$-uniqueness for Schr\"odinger operators which is ...
