A general framework for geometric dualities for varieties of algebras

4 pagesPublished: July 28, 2014

Abstract

We set up a framework that subsumes many important dualities in mathematics (Birkhoff, Stone, Priestly, Baker-Beynon, etc.) as well as the classical correspondence between polynomial ideals and affine varieties in algebraic geometry. Our main theorems provide a generalisation of Hilbert's Nullstellensatz to any (possibly infinitary) variety of algebras. The common core of the above dualities becomes then clearly visible and sets the basis to a canonical method to seek for a geometric dual to any given variety of algebras.

Keyphrases: algebraic geometry, Categorical adjunction, Galois adjunction, Hilbert Nullstellensatz, Stone dualities, topological duality, universal algebra
