Abstract
We prove, using variational methods, the existence in dimension two of positive vector ground states solutions for the Bose-Einstein type systems. The nonlinear interaction between two Bose fluids is assumed to be of critical exponential type in the sense of J. Moser. For ‘small’ solutions the system is asymptotically equivalent to the corresponding one in higher dimensions with power-like nonlinearities.
