Non-diffeomorphic minimal genus relative trisections of the same 4-manifold
Abstract
We show the existence of a 4-manifold with boundary that admits two non-diffeomorphic minimal genus relative trisections of the same (g,k;p,b)-type. To prove this, we introduce a simple operation that produces a trisection diagram of a closed 4-manifold from a relative trisection diagram.
