In this paper we study the space L p ( +), 1 p + , + being a positive definite matrix of measures. We prove that the set of all positive definite matrices of measures having the same moments as those of + is compact in the vague topology, and we give a density result for L 1 ( +) which is an extensi

Density effects and Ns co-doping of Kr solids doped with NO allow continuous tuning of the NO Rydberg state energies in a range 0.35 to 0.68 eV blue of the gas phase. This property is exploited to control the vibronic contiguration mixing between the Rydberg C \*II and the valence B \*lI states. The

In this paper we investigate nonlinear matrix equations X ± A \* X -q A = Q where q ≥ 1. We derive necessary conditions and sufficient conditions for the existence of positive definite solutions for these equations. We provide a sufficient condition for the equation X + A \* X -q A = Q to have two
