Constructs closed aspherical 4-manifolds that are homeomorphic but not diffeomorphic, providing counterexamples to the smooth Borel conjecture in dimension 4.
Derives Pohozaev compatibility between weak limit and bubble involving the Weyl tensor for Yang-Mills bubbling on general 4-manifolds, extending Yin's obstructions and ruling out some bubbling on CP2.
A new framework classifies PL-types for every triangulated 4-manifold with up to six pentachora, succeeding except on the 4-sphere, CP^2 and QS^4(2) where at most four, three and two types appear respectively.
T-positive links are precisely the strongly quasipositive links that are closures of T-homogeneous braids, strictly containing non-split braid positive links, with all strongly quasipositive fibered knots up to 12 crossings being T-positive.
An explicit maw dual graph construction extracts the Thurston norm from sutured manifold hierarchies, yielding computations for three-component pretzel link exteriors and a theorem that certain nonseparating surfaces in Haken manifolds lie outside open top-dimensional cones of the norm ball.
Establishes exact correspondence between diffusion sampling and adiabatic ground-state transport in Score Hamiltonians, yielding density reconstruction bounds and a fundamental sampling limit given by squared score error over spectral gap.
Exotic differential structures on S^7 produce different Dirac operator spectra for specific symmetric gauge potentials in the Kaluza-Klein limit, implying different physical laws on topologically identical manifolds.
Plebanski's chiral 2-form formulation of GR reveals additional structure in Einstein's equations and supplies new analytical and numerical tools.
A comprehensive introduction to spectral networks that develops higher-rank Teichmüller theory in parallel with class S gauge theory and BPS spectra.
