WebSep 17, 2024 · To measure the complexity of a “non-invertible” continuous map f on a compact metric space via the preimage structure, Hurley introduced the notion of pointwise topological preimage entropies h m (f) and h p (f) in 1995. A natural question was: Can one introduce the counterpart of h m (f) or h p (f) from the measure-theoretic point of view for … Web(ii) A composition of semi-algebraic maps is a semi-algebraic map; the image and preimage of a semi-algebraic set under a semi-algebraic map are semi-algebraic ... 44.
