Title: THH and cyclotomic structure.
Abstract: In this talk we will be looking at the construction of the topological Hochschild homology THH(R) where R is a ring spectrum. In the situation where R has the structure of a commutative ring spectrum then there is an equivalent description of THH(R) where certain structure becomes more easily constructed and we will explore what this provides for us. Time permitted variants of of THH will be discussed
