"Linearly degenerate PDE systems associated with 4-folds in Gr(3,5): integrability and classification"

I will discuss this particular class of coupled first order PDE systems in 3D (roughly equivalent to second order scalar equations) that take an intermediate position between linear and fully-nonlinear systems of PDEs. Based on the joint work with B.Doubrov, E.Ferapontov, V.Novikov.
