    Crucial aspects of the initial mass function. I. The statistical correlation between the total mass of an ensemble of stars and its most massive star
    Context. Our understanding of stellar systems depends on the adopted interpretation of the initial mass function, IMF φ(m). Unfortunately, there is not a common...

    Crucial aspects of the initial mass function. II. The inference of total quantities from partial information on a cluster
    Context. In a probabilistic framework of the interpretation of the initial mass function (IMF), the IMF cannot be arbitrarily normalized to the total mass, ℳ...
