چکیده
We characterize when Peetre's K -functional slowly decays to zero and we use this characterization demonstrate certain strict inclusions between real interpolation spaces.

the 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...
15 صفحه اولOn Decay of K-theory
Closed string tachyon condensation resolves the singularities of nonsupersymmetric orbifolds, however the resolved space typically has fewer D-brane charges than that of the orbifold. The description of the tachyon condensation process via a gauged linear sigma model enables one to track the topology as one passes from the sigma model’s “orbifold phase” to its resolved, “geometric phase,” and t...

15 صفحه اول1 B → K ∗ γ decay on APE ∗
We present results for the radiative decay B → K * γ, obtained by using the Clover action at β = 6.0 on APE. The compatibility between the scaling laws predicted by the Heavy Quark Effective Theory (HQET) and pole dominance is discussed. The final result depends crucially on the assumed q 2-dependence of the form factors.
متن کاملSlow k-Nim
Given n piles of tokens and a positive integer k ≤ n, we study the following two impartial combinatorial games Nimn,≤k and Nim 1 n,=k. In the first (resp. second) game, a player, by one move, chooses at least 1 and at most (resp. exactly) k non-empty piles and removes one token from each of these piles. For the normal and misère version of each game we compute the Sprague-Grundy function for th...
