Sesquilinear version of numerical range and numerical radius
Acta Universitatis Sapientiae, Mathematica, 2017 AbstractIn this paper by using the notion of sesquilinear form we introduce a new class of numerical range and numerical radius in normed space š¯’±, also its various characterizations are given. We apply our results to get some inequalities.

Scalar field configurations supported by charged compact reflecting stars in a curved spacetime
Physics Letters B, 2018 We study the system of static scalar fields coupled to charged compact reflecting stars through both analytical and numerical methods. We enclose the star in a box and our solutions are related to cases without box boundaries when putting the box far ...

Mass-radius relation of Newtonian self-gravitating Bose-Einstein condensates with short-range interactions. II. Numerical results [PDF]
Physical Review D, 2011 We develop the suggestion that dark matter could be a Bose-Einstein condensate. We determine the mass-radius relation of a Newtonian self-gravitating Bose-Einstein condensate with short-range interactions described by the Gross-Pitaevskii-Poisson system.
