Resumen de Central limit theorems for generic lattice point counting

Michael Björklund, Alexander Gorodnik

• We consider the problem of counting lattice points contained in domains in Rd defined by products of linear forms. For d≥9we show that the normalized discrepancies in these counting problems satisfy non-degenerate Central Limit Theorems with respect to the unique SLd(R)-invariant probability measure on the space of unimodular lattices in Rd. We also study more refined versions pertaining to “spiraling of approximations”. Our techniques are dynamical in nature and exploit effective exponential mixing of all orders for actions of diagonalizable subgroups on spaces of unimodular lattices.
