Abstract
Piecewise quasipolynomial growth of Presburger counting functions combines with tame persistent homology module theory to conclude piecewise quasipolynomial behavior of constructible families of finely graded modules over constructible commutative semigroup rings. Functorial preservation of constructibility for families under local cohomology, , and yield piecewise quasipolynomial, quasilinear, or quasiconstant growth statements for length of local cohomology, -invariants, regularity, depth; length of and Betti numbers; length of and Bass numbers; associated primes via -invariants; and extended degrees, including the usual degree, Hilbert-Samuel multiplicity, arithmetic degree, and homological degree.
