### On the Problem of Symmetrizability for Hyperbolic Systems of First Order

E.Yu.Panov

Abstract: It is shown that a general nonstrictly hyperbolic first order $n\times n$-system with $m$ spatial variables can be always symmetrized only in the cases when $n=2$ or $m=1$. Connection with symmetrizability (in Friedrich's sense) of scalar hyperbolic equations is considered. Some algebraic criterion of symmetrizability is also given.
