Existence of CR sections for high power of semi-positive generalized   Sasakian CR line bundles over generalized Sasakian CR manifolds
  Let $X$ be a compact generalized Sasakian CR manifold of dimension $2n-1$, $n\geqslant2$, and let $L$ be a generalized Sasakian CR line bundle over $X$ equipped with a rigid semi-positive Hermitian fiber metric $h^L$. In this paper we prove that if $h^L$ is positive at some point of $X$ and conditions Y(0) and Y(1) hold at each point of $X$, then $L$ is big.
