abstract = "Massive and super-massive black-holes (BH) can be find in the
center of all galaxies, according to the opinion from the
scientific community. However, an open question is to know the
origin of such BHs. One explanation is consider such objects
coming from the stars with large redshifts very old stars colapsed
during the ancient eras (population-III stars: the first-born
stars created in the universe). A framework to investigate this
scenario is to derive a mathematical model describing the
evolution of the black hole distribution. From the distribution
observed nowadays, the problem is formulated as an inverse problem
to determine a possible disrtibution for large redshift, where the
cost function is given by the square difference between the
observation and the model data under association with a
regularization operator. The regularized inverse solution can be
computed using an optimizer to identify the best solution for the
functional to be minimized. Preliminar results are shown using
synthetic observational data.",
