Permutation invariant lattices
Lenny Fukshansky, Stephan Ramon Garcia, Xun Sun
We say that a Euclidean lattice in is permutation invariant if its automorphism group has non-trivial intersection with the symmetric group , i.e., if the lattic…
On lattices generated by finite Abelian groups
Albrecht Boettcher, Lenny Fukshansky, Stephan Ramon Garcia +1
This paper is devoted to the study of lattices generated by finite Abelian groups. Special species of such lattices arise in the exploration of elliptic curves over finite fields.…
Toeplitz determinants with perturbations in the corners
Albrecht Boettcher, Lenny Fukshansky, Stephan Ramon Garcia +1
The paper is devoted to exact and asymptotic formulas for the determinants of Toeplitz matrices with perturbations by blocks of fixed size in the four corners. If the norms of the…
Wetzel's Problem, Paul Erdos, and the Continuum Hypothesis: a mathematical mystery
Stephan Ramon Garcia, Amy L. Shoemaker
This is a short historical note concerning the evolution of Wetzel's problem and Erdos' solution.
Mathematical and physical aspects of complex symmetric operators
Stephan Ramon Garcia, Emil Prodan, Mihai Putinar
Recent advances in the theory of complex symmetric operators are presented and related to current studies in non-hermitian quantum mechanics. The main themes of the survey are: the…
