Query: On regularly fibered complex surfaces   We show that a compact complex surface which fibers smoothly over a curve of
genus >1 with fibers of genus >1 fibers holomorphically. We deduce an
improvement of a result in [D Kotschick, Math. Research Letters, 5 (1998)
227-234], and a characterisation of fibered surfaces with zero signature.
