Let T be a complete discrete valuation ring and $\hat{ X}$ a smooth projective curve over $S=\spec(T)$ with closed fibre $X$. Denote by $F$ the function field of $\hat{ X}$ and by $\hat{ F}$ the completion of $F$ with respect to the discrete valuation defined by $X$, the closed fibre. In this paper, we construct indecomposable and noncrossed product division algebras over $F$. This is done by defining an index preserving group homomorphism $s:\br(\hat{ F})'\to\br(F)'$, and using it to lift indecomposable and noncrossed product division algebras over $\hat{ F}$.
