The authors are members of a Research Group on Functional Analysis that it is interdisciplinary research group mainly devoted to the study of mathematical problems in the area of the functional analysis and applications of this subject to other areas both of theoretical and applied science, as quantum mechanics and signal analysis in acoustics. The background of the members of this team is mainly functional analysis, physics and topology. Nowadays regarding the research in mathematics their publications are mainly devoted to classical and new problems of the general theory of Banach lattices,...
