T. Ibukiyama et H. Saito, ON ZETA-FUNCTIONS ASSOCIATED TO SYMMETRICAL MATRICES .3. AN EXPLICIT FORM OF L-FUNCTIONS, Nagoya Mathematical Journal, 146, 1997, pp. 149-183
In [I-S2], we gave an explicit form of zeta functions associated to th
e space of symmetric matrices. In this paper, the case of L-functions
is treated. In the case of definite symmetric matrices, we show the ra
tinality of special values of these L-functions.
