Descripción
We obtain the probability distribution for the volume of excursion sets
in a three-dimensional Gaussian field, in order to develop the
approximation to the cosmic mass function that follows directly from the
assumption that the spherical collapse criteria may be applied to field
points. We also use this distribution to develop an analytical treatment
for the best approach to deriving the cosmic mass function. By comparing
both approaches, we conclude that the spherical collapse criteria cannot
be applied to field points. We discuss the general conditions for the
validity of the analytical derivations of the cosmic mass function and
suggest how to remove their main source of uncertainty.
