Immersions of punctured 4-manifolds: with applications to Quantum Cellular Automata
arXiv:2208.03064 · doi:10.1090/tran/9546
Abstract
Motivated by applications to pulling back quantum cellular automata from one manifold to another, we study the existence of immersions between certain smooth 4-manifolds. We show that they lead to a very interesting partial order on closed 4-manifolds.
