Аннотация:We prove theorems on the exact asymptotic forms as u → ∞ of two functional integrals over the Bogoliubov measure μB of the forms
∫C[0,β][∫β0|x(t)|pdt]udμB(x),∫C(0,β)exp{μ(∫β0|x(t)|pdt)a/p}dμB(x)
for p = 4, 6, 8, 10 with p > p0, where p0 = 2+4π2/β2ω2 is the threshold value, β is the inverse temperature, ω is the eigenfrequency of the harmonic oscillator, and 0 < α < 2. As the method of study, we use the Laplace method in Hilbert functional spaces for distributions of almost surely continuous Gaussian processes.
