Remarks on a Quadratic Form of Duren and Schiffer

Remarks on Form Factor Bounds

Improved model independent upper bounds on the weak transition form factors are derived using inclusive sum rules. Comparison of the new bounds with the old ones is made for the form factors hA1 and hV in B → D decays. [email protected] 1 A set of model independent bounds has been derived to provide a restriction on the shape of weak transition form factors [1–3]. They have been extensive...

Quadratic Division Algebras Revisited ( Remarks On

In his remarkable article “Quadratic division algebras” (Trans. Amer. Math. Soc. 105 (1962), 202–221), J. M. Osborn claims to solve ‘the problem of determining all quadratic division algebras of order 4 over an arbitrary field F of characteristic not two . . . modulo the theory of quadratic forms over F ’ (cf. p. 206). While we shall explain in which respect he has not achieved this goal, we sh...

Remarks on Self-Inverse Quadratic Permutation Polynomials

Conditions for a quadratic permutation polynomial (QPP) to be self-inverse over the ring Zm of modular integers are given. If m = 2n, necessary and sufficient conditions for a QPP to be self-inverse are determined. Additional properties of QPP over modular integers as well as examples of monomial permutation polynomials are also provided. Mathematics Subject Classification: 12E10, 11B83

on translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach

abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
