Calderón Couples and K-divisibility (preliminary Version)
These lecture notes survey a number of topics from the classical and modern theory of interpolation of operators. One aim, after the general introduction, is to discuss a family of results which deal with the problems of describing all interpolation spaces with respect to given couples of Banach spaces. A second aim is to present the remarkable K−divisibility theorem of Brudnyi and Krugljak, in...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...

We present some sufficient conditions under which pairs of Banach function lattices are Calderón couples with special attention to the case of classical Lorentz spaces.
متن کاملHyers-Ulam stability of K-Fibonacci functional equation
Let denote by Fk,n the nth k-Fibonacci number where Fk,n = kFk,n−1+Fk,n−2 for n 2 with initial conditions Fk,0 = 0, Fk,1 = 1, we may derive a functionalequation f(k, x) = kf(k, x − 1) + f(k, x − 2). In this paper, we solve thisequation and prove its Hyere-Ulam stability in the class of functions f : N×R ! X,where X is a real Banach space.
متن کاملStudies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays
We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
