چکیده
Let Fq[x, y] be the polynomial algebra in two variables over the finite field Fq with q elements. We give an exact formula and the asymptotics for the number pn of automorphisms (f, g) of Fq[x, y] such that max{deg(f), deg(g)} = n. We describe also the Dirichlet series generating function p(s) = ∑

ALGEBRAS WITH CYCLE-FINITE STRONGLY SIMPLY CONNECTED GALOIS COVERINGS
Let $A$ be a nite dimensional $k-$algebra and $R$ be a locally bounded category such that $R rightarrow R/G = A$ is a Galois covering dened by the action of a torsion-free group of automorphisms of $R$. Following [30], we provide criteria on the convex subcategories of a strongly simply connected category R in order to be a cycle- nite category and describe the module category of $A$. We p...

متن کاملCoordinates and Automorphisms of Polynomial and Free Associative Algebras of Rank Three
We study z-automorphisms of the polynomial algebra K[x, y, z] and the free associative algebra K〈x, y, z〉 over a field K, i.e., automorphisms which fix the variable z. We survey some recent results on such automorphisms and on the corresponding coordinates. For K〈x, y, z〉 we include also results about the structure of the z-tame automorphisms and algorithms which recognize z-tame automorphisms ...
متن کاملDimension of Automorphisms with Fixed Degree for Polynomial Algebras
Let K[x, y] be the polynomial algebra in two variables over an algebraically closed field K. We generalize to the case of any characteristic the result of Furter that over a field of characteristic zero the set of automorphisms (f, g) of K[x, y] such that max{deg(f), deg(g)} = n ≥ 2 is constructible with dimension n + 6. The same result holds for the automorphisms of the free associative algebr...
متن کاملRelative order and type of entire functions represented by Banach valued Dirichlet series in two variables
In this paper, we introduce the idea of relative order and type of entire functions represented by Banach valued Dirichlet series of two complex variables to generalize some earlier results. Proving some preliminary theorems on the relative order, we obtain sum and product theorems and we show that the relative order of an entire function represented by Dirichlet series is the same as that of i...
