Abstract
It is well known that there are no minimal surfaces of constant curvature lying fully in the hyperbolic 4-space H 4(−1). In contrast, in this article we discover a minimal immersion of the hyperbolic plane \({H^2(-\frac{1}{3})}\) of curvature \({-\frac{1}{3}}\) into the neutral pseudo-hyperbolic 4-space \({H^4_2(-1)}\). Moreover, we prove that, up to rigid motions of \({H^4_2(-1)}\), this minimal immersion provides the only space-like parallel minimal surface lying fully in \({H^4_2(-1)}\).
