On the geometry of measures with density bounds in a Hölder anisotropic setting

Ignacio Tejeda

We study the regularity of the support of a Radon measure $μ$ on $R^{n + 1}$ for which anisotropic versions of its $n$ -dimensional density ratio and its doubling character ar…

Spectral properties of Landau Hamiltonians with non-local potentials

Esteban Cárdenas, Georgi Raikov, Ignacio Tejeda

We consider the Landau Hamiltonian $H_{0}$ , self-adjoint in $L^{2} (R^{2})$ , whose spectrum consists of an arithmetic progression of infinitely degenerate positive eigenvalues $…

Can we admit the way in which $sin (x)$ is typically defined?

Ignacio Tejeda

I review some facts which the usual sen(x) and cos(x) definitions are based on. The purpose of this paper is to show that this facts can be proved if we assume some basic ideas of…
