Research changelog · TFPT — Introduction and reading guide
v295_flataway_a2_exact.py ( FLATAWAY.A2.01) upgrades the v292 positive-definiteness from a numerical scan to a proof: the first variation of [formula in source] vanishes (zero-mean off-mark curvature, Gauss-Bonnet), and since [formula in source] is convex (Klein/Peierls), [formula in source] is the global minimum — so [formula in source] for all deformations, [formula in source] iff [formula in source] . The exact se
