Abstract: Partial Wave Analysis of the $\pi^+\pi^-\pi^-$ system produced by 29 GeV/c $\pi^-$ beam on berillium target is presented. About $30\cdot10^6$ events in the wide $|t'|$ range $0\ldots0.8\;GeV^2/c^2$ are collected with upgraded VES setup. The size of the data sample is 2.5 times larger than that previously analyzed by VES. Data are analyzed using formalism of density matrix with unlimited rank. We discuss status of the $a_1(1420)$, $a_2(1700)$, $a_3(1875)$ states, structure of exotic $\rho(770)\pi$ P-wave with $J^{PC}=1^{-+}$.
