Large Deviation Principle of Multidimensional Multiple Averages on $\mathbb{N}^d$

Abstract

This paper establishs the large deviation principle (LDP) for multiple averages on N d . We extend the previous work of [Carinci et al., Indag. Math. 2012] to multidimensional lattice N d for d ≥ 2. The same technique is also applicable to the weighted multiple average launched by Fan [Fan, Adv. Math. 2021]. Finally, the boundary conditions are imposed to the multiple sum and explicit formulae of the energy functions with respect to the boundary conditions are obtained.
