On spectral structure of bounded linear operators on reflexive Banach spaces
(Editorial Universidad de Sevilla, 2005)A descriptive characterization of point, continuous, and residual spectra of operators acting on a separable Hilbert space is obtained. The possible point spectra of bounded linear operators acting on lp, 1 < p < ∞ are characterized.

On the nonexistence of k-reptile simplices in R3 and R4
(2013)A d-dimensional simplex S is called a k-reptile (or a k-reptile simplex) if it can be tiled without overlaps by k simplices ...
