WebDec 22, 2004 · We show that the orbit of a point on a compact nilmanifold X under the action of a polynomial sequence of translations on X is well distributed on the union of several sub-nilmanifolds of X.This implies that the ergodic averages of a continuous function on X along a polynomial sequence of translations on X converge pointwise. WebIn this paper, we propose a pointwise QPP framework that allows us to evaluate the quality of a QPP system for individual queries by measuring the deviations between each prediction versus the corresponding true value, and then aggregating the results over a set of queries. clothing vendors usa
