Quadratic effective energy--momentum tensor on uniform-density hypersurfaces during slow-roll inflation
Inyong Cho
We investigate the quadratic-order effective energy--momentum tensor (2EMT) of scalar cosmological perturbations on uniform-density hypersurfaces during slow-roll inflation. The 2E…

Many-point tropical relaxation and the Monge--Ampère equation
Nikita Kalinin, Ernesto Lupercio, Higinio Serrano +1
The authors develop a tropical approximation scheme for the planar Aleksandrov Monge‑Ampère equation using concave tropical series defined by point clouds, and prove that the scale…

Residues of a tropical zeta function for convex domains
Nikita Kalinin, Ernesto Lupercio, Mikhail Shkolnikov
We define an -invariant tropical zeta function of a convex domain. In dimension 2 it admits boundary Dirichlet-series representation with summands…
