Title: Integrable vector evolution equations
Date and time: 15.01.2025, 17:00 (GMT +03:00)
Abstract: We consider evolution equations of the form $U_t=\sum_{i=1}^n a_i U_i$, where $U(x,t)$ is a vector of arbitrary size, $U_i=\frac{\partial^i U}{\partial x ^ i}$ and the coefficients $a_i$ are functions of scalar products $(U_i, U_j)$. The symmetry approach to classification of scalar evolution equations is generalised to the case of such vector isotropic evolution equations. A further generalisation to the anisotropic case is proposed. Some examples and classification results are presented.
