$T^3$-fibrations on compact six-manifolds
Abstract
Description
We describe a simple way of constructing torus fibrations $T^3\to X\to S^3$ which degenerate canonically over a knot or link in $S^3$. We show that the topological invariants of $X$ can be computed algebraically from the monodromy representation of the fibration. We use this to obtain some new $T^3$-fibrations $S^3\times S^3\to S^3$ and $(S^3\times S^3)#(S^3\times S^3)#(S^4\times S^2) \to S^3$ whose discriminant locus is a torus knot.
