This text has as a point of reflection the homages to black people, men and women, inscribed in the streets and squares of Sao Paulo, in different times of the republican period. The chosen ones were projected in the ...

This research entitled "Black Intellectual, Intellectual Black or Black-Intellectual: notes of the process of becoming Black-intellectual", aimed at understanding processes in which Black men and women have made himself / ...

We use the black hole entropy function to study the effect of Born-Infeld terms on the entropy of extremal black holes in heterotic string theory in four dimensions. We find, that after adding a set of higher curvature ...

The superradiant instability modes of ultralight massive vector bosons are studied for weakly charged rotating black holes in Einstein-Maxwell gravity (the Kerr- Newman solution) and low-energy heterotic string theory (the ...

Using the Sen’s entropy function formalism, we compute the entropy for the extremal dyonic black hole solutions of theories in the presence of dilaton field coupled to the field strength and a dilaton potential. We solve ...
