Recently the distributive equations involving various classes of aggregation operators have aroused widespread attention because of their importance in the theoretic and applied communities of fuzzy set theory. 2-uninorms and semi-t-operators are two special classes of aggregation operators and have been proved to be useful in many areas such as fuzzy decision making, approximate reasoning and ...

Recently the authors characterized Fredholmn properties of Toeplitz operators on weighted Fock spaces when Laplacian weight function is bounded below and above. In present work extend their characterization to doubling with a subharmonic whose measure. The geometry induced by Bergman metric for much more complicated than that Euclidean used in all previous cases study Fredholmness, which leads ...

One of the most fundamental problems in mathematics is to solve linear equations of the form Tf = g, where T is a linear transformation, g is known, and f is some unknown quantity. The simplest example of this comes from elementary linear algebra, which deals with solutions to matrix-vector equations of the form Ax = b. More generally, if V,W are vector spaces (or, in particular, Hilbert or Ban...
