摘要
In the present work, we investigate existence of deformations and algebraic approximability for certain uniruled Kahler threefolds. In the first part, we establish existence of infinitesimal deformations for all conic bundles with relative Picard number one over a non-algebraic compact Kahler surface S and existence of positive-dimensional families of deformations in all but some special cases. In the second part, we study the question of algebraic approximability for projective bundles over S and threefolds bimeromorphic to\documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$\mathbb {P}_1\times S$\end{document}.
