Aa. Bytsenko et Fl. Williams, ZETA-FUNCTIONS ON A PRODUCT OF EINSTEIN MANIFOLDS, AND THE MULTIPLICATIVE ANOMALY, Journal of mathematical physics, 39(2), 1998, pp. 1075-1086
The global additive and multiplicative properties of Laplace-type oper
ators acting on irreducible rank 1 symmetric spaces are considered. Th
e explicit form of the zeta function on product spaces and of the mult
iplicative anomaly is derived. (C) 1998 American Institute of Physics.
