Published in 2017 at "Mediterranean Journal of Mathematics"

DOI: 10.1007/s00009-017-1055-y

Abstract: In this paper, we discuss the existence of solutions for a 2nth-order differential equation with Sturm–Liouville operator. Using critical point theorems due to Bonanno and Candito, we prove that there exist at least three classical… read more here.

Published in 2019 at "Archive for Rational Mechanics and Analysis"

DOI: 10.1007/s00205-019-01387-4

Abstract: We establish the global existence of solutions to the compressible Euler equations, in the case that a finite volume of ideal gas expands into a vacuum. Vacuum states can occur with either smooth or singular… read more here.

Published in 2019 at "Communications in Mathematical Physics"

DOI: 10.1007/s00220-019-03469-6

Abstract: AbstractWe are concerned with Chern–Simons gauge theories of rank 2 in $$\mathbb {R}^2$$R2 such as SU(3), SO(5), and $$G_2$$G2 Chern–Simons theory. One can reduce the self-dual equations of these models to a $$2\times 2$$2×2 system… read more here.
