Uniqueness of Gibbs fields with unbounded random interactions on unbounded degree graphs

Gibbs fields with continuous spins are studied, the underlying graphs of which can be of unbounded vertex degree and the spin-spin pair interaction potentials are random and unbounded. A high-temperature uniqueness of such fields is proved to hold under the following conditions: (a) the vertex degree is of tempered growth, i.e., controlled in a certain way; (b) the interaction potentials $W_{xy}$ are such that $\|W_{xy}\|=\sup_{\sigma,\sigma'} |W_{xy}(\sigma, \sigma')|$ are independent (for different edges $\langle x, y \rangle$), identically distributed and exponentially integrable random variables.
