We dedicate this paper to his memoryAbstract: The Weierstrass semigroup of pole orders of meromorphic functions in a point p of a smooth algebraic curveC is a classical object of study; a celebrated problem of Hurwitz is to characterize which semigroups S ¼ N with finite complement are realizable as Weierstrass semigroups S = S(C, p). In this note, we establish realizability results for cyclic covers ƒÎ : (C, p) ¨ (B, q) of hyperelliptic targets B marked in hyperelliptic Weierstrass points; and we show that realizability is dictated by the behavior under j -fold multiplication of certain divisor classes in hyperelliptic Jacobians naturally associated to our cyclic covers, as j ranges over all natural numbersFechadoUNIVERSIDADE ESTADUAL DE CAMPINASCotterill, Ethan, 1979-Pflueger, TherezaZhang, Naizhen2023info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/20.500.12733/14255COTTERILL, Ethan; PFLUEGER, Thereza; ZHANG, Naizhen.
