PROPAGATORS AND DILATIONS ON PSEUDO-HILBERT SPACES
Journal Title: Journal of Science And Arts - Year 2011, Vol 15, Issue 2
Abstract
In this paper we shall try to transpose the conditions of the existence of propagators for kernel on *-semigroups, notion introduced by P. Masani [6]. We will start with a few additional observations concerning *-representations and then we will present some properties of propagators and dilations.

CONSIDERATIONS ON THE STABILIZED EQUILIBRIUM OF THE HOT PLASMA
We introduce a variational problem on a Sobolev space associated with an eigenvalue problem for a magnetic flux, characterizing the quasi-static equilibrium of plasma. We obtain the existence and regularity results of a...
THE DYNAMICS OF TRACE ELEMENTS IN DNIESTER RIVER ECOSYSTEMS
The goal of this research was to investigate the dynamics of trace metals (Cu, Zn, Mn, Co, Ni, Mo, V, Pb, Cd etc) in water, sediments, and the accumulation in the plants, invertebrates and organs and tissue of Cyprinidae...
ENVIRONMENTAL RESEARCHES - A WAY OF GUIDING HIGH SCHOOL STUDENTS TO SCIENTIFIC RESEARCH
An air quality study using lichens as biomonitors was done by involving of high school students. After a detailed describing of every stage of the research and their personal studies, they have participated on the select...
ON AN INEQUALITY FOR THE MEDIANS OF A TRIANGLE
In this paper, we give two new simpler proofs of a sharp inequality for the medians of a triangle. We also establish two new inequalities by using this sharp inequality. Some related conjectures checked by the computer a...
