Free-surface equatorial flows with surface tension in spherical coordinates
Andrei Stan
In this paper, we determine an exact solution to the governing equations in spherical coordinates for an inviscid, incompressible fluid. This solution describes a steady, purely az…

A mutual control problem for semilinear system via fixed point approach
Radu Precup, Andrei Stan
In this paper, we introduce and discuss the concept of a mutual control problem. Our analysis relies on a vector fixed-point approach based on the fixed-point theorems of Perov, Sc…
