Finite-n Chernoff Errors under Laplace Transformation: Stationary Singularities, Scaling, and Chebyshev Control.

Shift-family Chernoff approximations of the heat semigroup produce a movinghigh-frequency "comb" artifact on non-smooth data at any finite number ofcompositions n. This note shows what happens to the comb under Laplacetransformation (the resolvent route): it decomposes **exactly*...
