A hypersurface evolution is an evolution between spacelike hypersurfaces in the relativistic quantum theory under consideration. It satisfies interaction locality and propagation l…

Let $\Sigma$ be an arbitrary Cauchy surface, and suppose it is approximated by a surface that is piecewise flat but non-horizontal. Piecewise-flat approximation conjecture. Such an…

Let $P_\ell\subseteq\Sigma$ be a portion of a Cauchy surface approximated by detector regions $B_{k\ell}$ on horizontal pieces $B_k$, and let $p_\ell$ be the limiting probability o…

Wheeler–Feynman conjecture. Field theory and delayed action-at-a-distance are complementary manifestations of the same physics.

Let $A:\mathbb{R}^4\to\mathbb{R}^4$ be a smooth 1-form satisfying the stated decay condition, and let the profile function and the operators $\mathscr{H}_\Sigma$, $U_\Sigma$, and…
