Interaction of a black hole with scalar field in cosmology background
Malik Almatwi
Recent data from elliptical galaxies indicate that the growth in the masses of black holes exceeds what is expected from the accretion of surrounding matter, and this growth appear…

Spin current in BF theory
Malik Matwi
In this paper, we introduce a current which we call spin current corresponding to the variation of the matter action in BF theory with respect to the spin connection which take…
