I will define the Zariski topology in a more general setting---on the spectrum of a commutative ring with identity, which provides the starting point for the construction of affine schemes---giving extensive examples to illustrate its construction and separation properties.

Gelfand, Serconek, Retakh and Wilson defined algebras they call A(G) associated to layered graphs G. These algebras arise in the context of factoring polynomials over non-commutative rings.
Symplectic topology and geometry is the staging ground for classical
mechanics. During the last 20 years, much progress in the understanding
of basic problems in symplectic topology and geometry has been made via the tools of J-holomorphic curves.
Torsors are entities which arise, among other places, in
differential geometry and Galois theory. In this introductory talk the
connection with Galois theory will be emphasized
