Large deviation principle for multidimensional second compound renewal processes in the phase space

We obtain the large deviation principles for multidimensional second compound renewal processes $\mathbf{Y}(t)$ in the phase space $\mathbb{R}^d$, for this we find and investigate the rate function $D_Y(\alpha)$. Also we find asymptotics for the Laplace transform of this process when the time goes to infinity, for this we find and investigate the so-called fundamental function $A_Y(\mu)$.
