DESCRIPTION:Speaker: Orla McGrath (University of Leeds)\n\nTitle: Partial
  Difference Algebraic Groups\n\nAbstract: A difference algebraic group i
 s a subgroup of the general linear group defined by difference equations
 . Groups definable in ACFA (algebraically closed fields with an automorp
 hism) have been widely studied\, with applications including the proof o
 f the Manin-Mumford conjecture. In contrast\, partial difference fields 
 do not admit a model companion\, so instead we use an algebro-geometric 
 approach to study groups defined over fields with finitely many commutin
 g endomorphisms. In this talk I will introduce these partial difference 
 algebraic groups and present some initial results\, including the finite
 ness of their defining ideals and the existence of a dimension polynomia
