Eigenvalues of even very nice Toeplitz matrices can be unexpectedly erratic
Mauricio Barrera, Albrecht Boettcher, Sergei M. Grudsky +1
It was shown in a series of recent publications that the eigenvalues of Toeplitz matrices generated by so-called simple-loop symbols admit certain regular asymptotic ex…
Lattices from tight equiangular frames
Albrecht Boettcher, Lenny Fukshansky, Stephan Ramon Garcia +2
We consider the set of all linear combinations with integer coefficients of the vectors of a unit tight equiangular frame and are interested in the question whether this se…
From convergence in distribution to uniform convergence
Johan Manuel Bogoya, Albrecht Boettcher, Egor A. Maximenko
We present conditions that allow us to pass from the convergence of probability measures in distribution to the uniform convergence of the associated quantile functions. Under thes…
