Simple $E_0$ semigroups and its generalisations
Dr. R. Srinivasan

After defining the notion of an $E_0$-semigroup, we will consider the simplest examples of $E_0$ semigroup, on the algebra of all bounded operators on Hilbert space. We will generalise those $E_0$ semigroups to get some exotic $E_0$ semigroups.
