On the moduli space of multi-fractional instantons on the twisted
This paper investigates the moduli space of multi-fractional instantons on a twisted by demonstrating that 't Hooft's constant field strength solutions constitute the entire moduli space only when , whereas for , they represent a measure-zero subset surrounded by non-constant, non-abelian solutions, a finding that resolves a recent puzzle and is validated through analytical, numerical, and lattice comparisons.
