Signed sumsets and restricted signed sumsets in groups and fields
Establishes extremal bounds for h-fold signed sumsets in abelian groups when A intersects -A, plus polynomial-method lower bounds for restricted signed sumsets in arbitrary fields and specific bounds for small h when A and -A are disjoint.
