Ph CS 219A Lecture 7B Bell Polytope

The concept defines a local configuration in quantum foundations where joint probabilities for deterministic outputs factorize into products of Dirac delta functions conditioned solely on individual party inputs and predetermined values. This formalism distinguishes between strictly local deterministic strategies, which depend only on one's own input, and non-local configurations within the broader theory of Bell polytopes, allowing output dependence on remote inputs while maintaining determinism via generalized Delta constraints. The domain is quantum information theory and causal structure analysis, specifically addressing the geometric boundaries defined by convex hulls of these configurations to derive Bell inequalities through polar decomposition methods.
