The Theta Correspondence for Similitudes
In this paper we investigate the theta correspondence for similitudes over a nonarchimedean local field. We show that the two main approaches to a theta correspondence for similitudes from the literature are essentially the same, and we prove that a version of strong Howe duality holds for both constructions. Suppose that k is a nonarchimedean local field, X is a finite dimensional nondegenerat...
متن کاملClassification , Construction , and Similitudes of Quadratic Forms
We present a theory of classifying quadratic forms over an algebraic number field which is a reformulation of Eichler’s methods and different from the traditional theory of Hasse. As applications we determine all possible values of the discriminant of an integer-valued quadratic form over Q with a given dimension and index, and also the number of genera of such forms. We also investigate purely...
متن کاملCOMPARATIVE STUDIES OF SOLVATOCHROMISM BEHAVIOUR OF COPPER(I1) AND NICKEL(I1) SCHIFF BASE COMPLEXES
A series of Schiff Bases of Ni(II) and Cu(II) using acetylacetone (acac), salicylaldehyde (sal), ethylenediamine (en), and o-phenylendiarnine (dabe) were prepared and characterized. The electronic spectra of some copper chelates in various organic solvents depend strongly on the solvent used and the d-d band of Cu(II) shifts to red with the increase of the Donor Number (DN) of solvent. The ...
متن کاملOn groups of similitudes in associative rings
Let R be an associative ring with 1 and R the multiplicative group of invertible elements of R. In the paper, subgroups of R which may be regarded as analogues of the similitude group of a non-degenerate sesquilinear reflexive form and of the isometry group of such a form are defined in an abstract way. The main result states that a unipotent abstractly defined similitude must belong to the cor...
متن کاملSobre núcleos, distancias y similitudes entre intervalos
Existe un buen número de aplicaciones en las que la información a codificar viene expresada en forma de un intervalo de valores. Esto sucede, en especial, cuando se intentan procesar los datos por predicción a un cierto tiempo, como en el estudio del transitorio de un sistema de control, o en el análisis de la evolución financiera de una empresa. En este trabajo se presenta y desarrolla la defi...
