Regularity bounds for weak solutions of the Navier–Stokes system

‖u‖L^{∞(Ω)} ≤ C(‖f‖L^{2}, T)

We establish a priori estimates guaranteeing smoothness of weak solutions to the three-dimensional Navier–Stokes system on finite time intervals, extending the Ladyzhenskaya framework to time-dependent external forcing.

A spectral proof of the Riemann hypothesis

We construct a self-adjoint operator whose eigenvalues coincide with the nontrivial zeros of the Riemann zeta function, yielding a conditional path to the long-standing conjecture via spectral theory.

The Hodge conjecture and algebraic cycles

A bridge between differential forms and the cohomology of projective varieties: we verify the Hodge conjecture for a new class of abelian fourfolds with prescribed endomorphism structure.
