    报告摘要:Consider a constant vector field  $X = (1, \alpha)$ on $\mathbb{T}^2$. Multiply $X$ by a smooth function $f$ which is positive everywhere except at two points $p$ and $q$, where it vanishes. Let $\phi^t$ be the flow associated to this vector field. One can show that, for such a flow, the only invariant probability measures are combinations of Dirac measures at the points $p$ and $q$. A natural question arises: what happens to the time averages of $\phi^t(x)$ for a Lebesgue-typical point $x \in \mathbb{T}^2$ as $t$ tends to infinity? In this talk I will give some answers to that question.


    This is a joint work with Pierre-Antoine Guihéneuf (Université Paris 6, France).
