Research changelog · TFPT — Introduction and reading guide
v389 ( GRAV.LOOP.FINITE.01) — the entire-form-factor graviton is UV-finite at the loop level. The honest next step past v386 (which established the tree amplitude), extending v304/ v370/ v380/ v386 from the propagator to the superficial degree of divergence of loop graphs. This is the standard infinite-derivative / nonlocal-gravity finiteness statement (Tomboulis; Biswas–Mazumdar–Siegel; Modesto), not a full proof of
