By A. Barvinsky and D. Nesterov

We discuss various issues associated with the calculation of the reduced functional determinant of a special second order differential operator *\boldmath*{F}* =-d^2/d\tau^2+\ddot g/g*, *\ddot g\equiv d^2g/d\tau^2*, with a generic function *g(\tau)*, subject to periodic and Dirichlet boundary conditions. These issues include the gauge-fixed path integral representation of this determinant, the... Show more
