A description on the theory of Abelian functions for general trigonal curves of degree four is also included.AMS-TeX, 18 pages, Added a description on Abelian functions for general trigonal curves of degree fourNumber TheoryAlgebraic GeometryAbelian functions for trigonal curves of degree four and determinantal formulae in purely trigonal casetext
