Almost-sure normalized log posterior odds
OpenQAlgorithms.Papers.Independent.Intakethird100.P80.bayesian_limit69Fix a finite quantum experiment , a setting law , and an iid trial sequence distributed as on the product sigma algebra. The competing laws are all potential-outcome local models . Let be a continuous prior density on , normalized for its intrinsic affine-dimensional volume, with uniformly. Fix a prior hypothesis probability . For a sample , define
The density is integrable, the iid law has mass one, the target is finite, and almost surely all quantum and Bayesian sample likelihoods are positive and
This is the first-order Bayesian evidence rate proved in (69), with a sublinear log-odds remainder. It does not assert the stronger pathwise logarithmic remainder printed in (46).

What the Lean code literally says, in plain math · gpt-6.1-sol
Let specify a positive finite number of parties, a positive finite number of settings for each party, and a positive finite number of outcomes for every party and setting. Write for the set of joint settings, for the joint outcomes at setting , for the set of assignments prescribing an outcome for every party at every one of its settings, and for the outcomes prescribed at . Let be a real table satisfying these hypotheses: each is nonnegative and sums to ; for every subset of parties, settings agreeing on , and , the sums of over outcomes satisfying for and of over outcomes satisfying for are equal; and there exist positive local dimensions , a positive semidefinite matrix of trace on the joint index set , and positive semidefinite matrices , summing to the identity over for each , such that , where . Let be any nonnegative distribution of total mass on , allowing zero coordinates. For a distribution on , set , and on the trial set set and . Define if some trial has and , and otherwise define it as , viewed in , and put , where is the simplex of distributions on . Let be Hausdorff measure of dimension , restricted to this simplex, and let be continuous on the simplex, satisfy there for some real , and satisfy . Finally let satisfy . For a finite trial sample , define , , and ; let be the infinite product of the trial measure . The conclusion is that is integrable with respect to , has total mass , , and for -almost every infinite trial sequence ,
