Decomposing Perfect Discrete Morse Functions on Connected Sums of 3-manifolds
Abstract
In this paper, we show that if a closed, connected, oriented 3-manifold M =
M1#M2 admits a perfect discrete Morse function, then one can decompose this
function as perfect discrete Morse functions on M_1 and M_2. We also give an
explicit construction of a separating sphere on M corresponding to such a
decomposition.
