In this paper the phase structure of the dense quark matter has beeninvestigated in the presence of baryon ${\mu}_B$, isospin ${\mu}_I$, chiral${\mu}_{5}$ and chiral isospin ${\mu}_{I5}$ chemical potentials in theframework of Nambu--Jona-Lasinio model. It has been shown that in thelarge-$N_{c}$ limit ($N_{c}$ is the number of quark colours) there exist threeduality correspondences in the model. The first duality is between the chiralsymmetry breaking and the charged pion condensation phenomena. And there aretwo new dualities that hold only for chiral symmetry breaking and charged pioncondensation phenomena separately. It was shown that at nonzero chiral${\mu}_{5}$ chemical potential chiral isospin ${\mu}_{I5}$ chemical potentialcan generate charged pion condensation in dense quark matter even with zero${\mu}_{I}$. But ${\mu}_{5}$ alone (in absence of ${\mu}_{I5}$ chemicalpotential) can generate this phase but not as powerfully as ${\mu}_{I5}$ doesand only at comparatively low baryon densities.

Dualities in dense quark matter with isospin, chiral and chiral isospin imbalance in the framework of the large-N$_{c}$ limit of the NJL$_{4}$ model
