The Hot Spots constant for bounded smooth domains was recently introduced by Steinerberger as a means to control the global extrema of the first nontrivial eigenfunction of the Neumann Laplacian by its boundary extrema. We generalize the Hot Spots constant to bounded Lipschitz domains and show that it leads to a necessary and sufficient condition for the weak Hot Spots conjecture HS2 of Bañuelos and Burdzy (J. Funct. Anal.164(1), 1–33, ). We also derive a new general formula for a dimension-dependent upper bound that can be tailored to any specific class of domains. This formula is then used to compute upper bounds for the Hot Spots constant of the class of all bounded Lipschitz domains infor both smalldand for asymptotically largedthat significantly improve upon the existing results.
