 Title: Weierstrass Points with First Non-Gap Four on a Double Covering of a Hyperelliptic Curve II Authors: Komeda, JiryoOhbuchi, Akira Keywords: Weierstrass Semigroup of a PointDouble Covering of a Hyperelliptic Curve4-Semigroup Issue Date: 2008 Publisher: Institute of Mathematics and Informatics Bulgarian Academy of Sciences Citation: Serdica Mathematical Journal, Vol. 34, No 4, (2008), 771p-782p Abstract: A 4-semigroup means a numerical semigroup whose minimum positive integer is 4. In [7] we showed that a 4-semigroup with some conditions is the Weierstrass semigroup of a ramification point on a double covering of a hyperelliptic curve. In this paper we prove that the above statement holds for every 4-semigroup. Description: 2000 Mathematics Subject Classification: Primary 14H55; Secondary 14H30, 14J26.
