E. Elizalde, ZETA-FUNCTION REGULARIZATION IS UNIQUELY DEFINED AND WELL, Journal of physics. A, mathematical and general, 27(9), 1994, pp. 120000299-120000304
Hawking's zeta-function regularization procedure is shown to be rigoro
usly and uniquely defined, thus putting an end to the spreading lore a
bout different difficulties associated with it. Basic misconceptions,
misunderstandings and errors which keep appearing in important scienti
fic journals when dealing with this beautiful regularization method-an
d other analytical procedures-are clarified and corrected.
