A new example of the effects of a singular background on the zeta function
(IOP Publishing, 2020-11)
Para motivar nuestra discusión, consideramos un campo escalar dimensional 1 + 1 que interactúa con un fondo estático de tipo Coulomb, de modo que el espectro de fluctuaciones cuánticas está dado por un operador diferencial ...
The multiplicative anomaly of three or more commuting elliptic operators
(INT PRESS BOSTON, 2015)
zeta-regularized determinants are well-known to fail to be multiplicative, so that in general det(zeta)(AB) not equal det(zeta)(A) det(zeta)(B). Hence one is lead to study the n-fold multiplicative anomaly
M-n(A(1),..., ...
Unusual poles of the zeta-functions for some regular singular differential operators
(IOP Publishing, 2003-12)
We consider the resolvent of a system of first order differential operators
with a regular singularity, admitting a family of self-adjoint extensions. We
find that the asymptotic expansion for the resolvent in the general ...
Zeta-function regularization of holographic Wilson loops
(American Physical Society, 2018-08)
Using zeta-function regularization, we study the one-loop effective action of fundamental strings in AdS5 xS5 dual to the latitude 1/4-BPS Wilson loop in N=4 super-Yang-Mills theory. To avoid certain ambiguities inherent ...
