    The subspace problem for weighted inductive limits of spaces of holomorphic functions
    We construct a countable inductive limit of weighted Banach spaces of holomorphic functions, which is not a topological subspace of the corresponding weighted...

    The Substellar Domain in the ɛ Orionis Cluster
    We present an IZ photometric survey covering a total area of about 1000 arcmin2 around the ɛ Orionis young massive star (˜10 Myr, d=412 pc) and reaching a...

    The Substellar Mass Function in the Central Region of the Open Cluster Praesepe from Deep LBT Observations
    Studies of the mass function (MF) of open clusters of different ages allow us to probe the efficiency with which brown dwarfs (BDs) are evaporated from clusters...

    The Substellar Population in the Young σ Orionis Cluster, Spatial Distribution
    We review different surveys, in the optical and infrared, conducted in the very young (age 1 8 Myr), nearby (d ˜ 350 pc) σ Orionis cluster aimed to characterize...

    The Substellar Population in σ Orionis
    The σ Orionis cluster (˜3 Myr, 350 pc) is an ideal site to investigate the early evolution of substellar (brown dwarf and planetary mass) objects. To date, the...

    The Substellar Population of the σ Orionis Cluster
    We present a deep I, Z photometric survey (I compl = 22 mag) covering a total area of 1.12 deg2 in the σ Orionis cluster. Using I, I - Z color-magnitude...
