Abstract

Using a direct procedure of calculation of zero-curvature representations (ZCR), we find a previously unknown hyperbolic equation which possesses an \(\mathfrak{s}\mathfrak{l}_2 \)-valued ZCR. This ZCR admits no parameters and is not reducible to a proper subalgebra of \(\mathfrak{s}\mathfrak{l}_2 \).
