Abstract: | We propose a procedure for calculating heat kernel coefficients and use it to derive the expression for any heat kernel coefficient B
i for an arbitrary profile of the throat. We give an explicit form of these coefficients up to B
3. We study domains of possible existence of wormholes for different values of the throat length-to-radius ratio and a nonminimal coupling constant. |
