  Spin-polarized transport through a quantum dot side attached to a topological
superconductor and coupled to a pair of normal leads is discussed in Coulomb
and Kondo regimes. For discussion of Coulomb range equation of motion method
with extended Hubbard I approximation is used and Kondo regime is analyzed by
Kotliar-Ruckenstein slave boson approach. Apart from the occurrence of zero
bias anomaly the presence of Majorana states reflects also in splitting of
Coulomb lines. In the region of Coulomb borders the spin dependent negative
differential conductance is observed. Due to the low energy scale of Kondo
effect this probe allows for detection of Majorana states even for extremely
weak coupling with topological wire. In this range no signatures of Majorana
states appear in Coulomb blockade dominated transport.
