摘要

We discuss application of generalized Weierstrass elliptic functions to finding solutions of nonlinear third order elliptic systems including the Cauchy-Riemann operators \({\partial }_{\overline{z} }\) z ¯ and ∂z with independent variables \(\overline{z }\) z ¯ = x - iy, z = x + iy and such that \(2{\partial }_{\overline{z} }\) 2 z ¯ = ∂x + iy and 2∂z = ∂x - iy. We find invariants of the Weierstrass functions depending on coefficients of the equations.
