Analytic investigation of the compatibility condition and the initial evolution of a smooth velocity field for the Navier-Stokes equation in a channel configuration
Péter Tamás Nagy, György Paál
A partial differential equation has usually a regular solution at the initial time if the initial condition is smooth in space, fulfills the governing equations and is compatible w…

An Ambarzumian type theorem on graphs with odd cycles
Márton Kiss
We consider an inverse problem for Schrödinger operators on a connected equilateral graph with standard matching conditions. The graph consists of at least two odd cycles g…

Spectral determinants and an Ambarzumian type theorem on graphs
Márton Kiss
We consider an inverse problem for Schrödinger operators on connected equilateral graphs with standard matching conditions. We calculate the spectral determinant and prove that the…
