N = 2 supergravity models based on the nonsymmetric quaternionic manifolds. I. Symmetries and Lagrangians

V. A. Tsokur, Yu. M. Ziniviev

In this paper we consider the N = 2 supergravity models in which the hypermultiplets realize the nonlinear sigma-models, corresponding to the nonsymmetric (but homogeneous) quatern…
