Integral Local Invariant Cycles in Degree One
For a semistable one-parameter family of complex projective varieties with smooth nearby fiber $X_t$ and monodromy $T$, is the map $H^1(X, \mathbb{Z}) \to H^1(X_t, \mathbb{Z})^T$ surjective? True in degree one, although the integral statement fails in higher degree.
