A. Conca, DIVISOR CLASS GROUP AND CANONICAL CLASS OF DETERMINANTAL RINGS DEFINED BY IDEALS OF MINORS OF A SYMMETRICAL MATRIX, Archiv der Mathematik, 63(3), 1994, pp. 216-224
In this paper we study the rings defined by ideals of minors, not nece
ssarily of fixed size, of a symmetric matrix of indeterminates. We pro
ve that they are normal, compute the divisor class group and the canon
ical class. We determine the Gorenstein rings among the rings under co
nsideration.
