A new invariant of 4-manifolds
We define an integer invariant [Formula: see text] of a smooth, compact, closed 4-manifold [Formula: see text] by minimizing a certain complexity of a trisection of [Formula: see text] over all trisections. The good feature of [Formula: see text] is that when [Formula: see text] and [Formula: see te...
