Title:A journey from Gauss's lemma to Prufer domains to Gaussian rings.

Speaker: Prof. Viji Thomas, TIFR Bombay

Abstract:We will discuss the basic properties of Prufer domains and Gaussian rings. We will briefly talk about Kaplansky's conjecture and we will prove that a domain is Prufer iff if it is Gaussian. If time permits, we will talk about weak global dimension of Gaussian rings.
