Description
Calorons are finite action solutions to (anti-)selfdual Yang-Mills equations on partially compact space S^1 times R^3.
These objects can be constructed as a periodic array of instantons in R^4 naively, however, the topological character of calorons is quite different from that of instantons. In this talk, we focus on this difference and re-examine the prior research on the topological character of calorons.
