Essential Dimension of Separable Algebras Embedding in a Fixed Central Simple Algebra
One of the key problems in non-commutative algebra is the classification of central simple algebras and more generally of separable algebras over fields, i.e., Azumaya-algebras whose center is étale over the given field. In this paper we fix a central simple F -algebra A of prime power degree and study seperable algebras over extensions K/F , which embed in AK . The type of such an embedding is...
متن کاملUpper bounds for noetherian dimension of all injective modules with Krull dimension
In this paper we give an upper bound for Noetherian dimension of all injective modules with Krull dimension on arbitrary rings. In particular, we also give an upper bound for Noetherian dimension of all Artinian modules on Noetherian duo rings.
متن کاملOn dimension of a special subalgebra of derivations of nilpotent Lie algebras
Let $L$ be a Lie algebra, $mathrm{Der}(L)$ be the set of all derivations of $L$ and $mathrm{Der}_c(L)$ denote the set of all derivations $alphainmathrm{Der}(L)$ for which $alpha(x)in [x,L]:={[x,y]vert yin L}$ for all $xin L$. We obtain an upper bound for dimension of $mathrm{Der}_c(L)$ of the finite dimensional nilpotent Lie algebra $L$ over algebraically closed fields. Also, we classi...

Modular invarinat, constraints the spectrum of the theory. Using the medum temprature expansion, for first and third order of derivative, a universal upper bound on the lowest primary field has been obtained in recent researches. In this paper, we will improve the upper bound on the scaling dimension of the lowest primary field. We use by the medium temprature expansion for an arbitrary orders...
متن کاملEssential Dimension of Simple Algebras with Involutions
Let 1 ≤ m ≤ n be integers with m|n and Alg n,m the class of central simple algebras of degree n and exponent dividing m. In this paper, we find upper bounds for the essential (2)-dimension of Alg n,2 . Moreover, we find a stronger upper bound for the essential 2-dimension of Alg n,2 over a field F of char(F ) 6= 2. As a result, we show that ed2(Alg16,2) = 24 over a field F of char(F ) 6= 2.
