The first half of the talk will be a survey on the class of almost nonnegatively curved manifolds. Here the curvature means sectional curvature or Ricci curvature. Then I will talk about a recent joint work with CHEN Xiaoyang and HAN Fei, in which vanishing theorems on certain genus of these manifolds are proved under an extra necessary assumption on the fundamental group.
