Abstract

A geometric description of a class of integrable evolution PDE systems involves anane connection and a covariantly constant tensor of rank (1; 3). Integrability imposes strongconditions on both the ane connection and on the tensor. In particular, the tensor turns outto be a deformation of a triple Jordan system. The goal of the project is an investigation of theabove geometrical structures and a construction of new examples of corresponding integrablemodels. (AU)
