Strong mixing and uniform density conjecture for LLL coefficients
Strong mixing and uniform density conjecture for LLL coefficients
Let be a “generic” distribution on the set of bases in used to sample inputs for LLL. For the pile toppled at iteration , let denote its index, so that is a random variable determined by the input distribution.
LLL mixing and density conjecture. (i) The sequence is strongly mixing as a stochastic process. (ii) Each is contained in a compact subset of the set of all probability density functions on with respect to the -norm, where is independent of the dimension, the input distribution, and any other variable.
This is proposed as a rigorous version of the claim that LLL is essentially a sandpile model. The first part formalizes the heuristic that widely separated coefficients are nearly independent; the second asserts a dimension- and distribution-independent compactness property. The source gives no resolution of either assertion.
