On Strong Going-Between, Going-Down, And Their Universalizations, II

David E. Dobbs, Gabriel Picavet (2003)

Annales mathématiques Blaise Pascal

Similarity:

We consider analogies between the logically independent properties of strong going-between (SGB) and going-down (GD), as well as analogies between the universalizations of these properties. Transfer results are obtained for the (universally) SGB property relative to pullbacks and Nagata ring constructions. It is shown that if A B are domains such that A is an LFD universally going-down domain and B is algebraic over A , then the inclusion map A [ X 1 , , X n ] B [ X 1 , , X n ] satisfies GB for each n 0 . However, for any...

Multiplicity estimate for solutions of extended Ramanujan’s system

Evgeniy Zorin (2012)

Journal de Théorie des Nombres de Bordeaux

Similarity:

We establish a new for solutions of a differential system extending Ramanujan’s classical differential relations. This result can be useful in the study of arithmetic properties of values of Riemann zeta function at odd positive integers (Nesterenko, 2011).

Centers in domains with quadratic growth

Agata Smoktunowicz (2005)

Open Mathematics

Similarity:

Let F be a field, and let R be a finitely-generated F-algebra, which is a domain with quadratic growth. It is shown that either the center of R is a finitely-generated F-algebra or R satisfies a polynomial identity (is PI) or else R is algebraic over F. Let r ∈ R be not algebraic over F and let C be the centralizer of r. It is shown that either the quotient ring of C is a finitely-generated division algebra of Gelfand-Kirillov dimension 1 or R is PI.
