SUMMARY:Dietmar Ebert(HU Berlin) - Competition and duality correspondence b
 etween chiral and superconducting channels in (2+1)-dimensional four-fermi
 on models
DESCRIPTION:The talk considers the duality correspondence between fermion-a
 ntifermion and difermion interaction channels as established in two (2+1)
 -dimensional Gross-Neveu type models with a fermion number chemical potent
 ial $\\mu$\nand a chiral chemical potential $\\mu_5$. The role and influen
 ce of this property on the phase structure of the models are investigated.
  In particular\, it is shown that the chemical potential $\\mu_5$ promotes
  the appearance of dynamical chiral symmetry breaking\, whereas the chemic
 al potential $\\mu$ contributes to the emergence of superconductivity.
