## EVENT DETAILS AND ABSTRACT

**Dynamical Systems Seminar**
**Title:** Nonconventional Polynomial Ergodic Averages and Flows

**Speaker:** Amanda Potts

**Speaker Info:** Northwestern

**Brief Description:**

**Special Note**:

**Abstract:**

Let (X,m) be a probability space, {T_t}_{t\in \R} an ergodic
flow, and f a bounded function on X. We will discuss the L^2-convergence
of averages of the form
1/T \int_0^T f(T_{p_1(t)} x) f(T_{p_2(t)} x) ... f(T_{p_k(t)} x) dt,
where p_1, p_2,..., p_k are nonconstant essentially distinct real valued
polynomials.
