Duality equations on a 4-manifold of conformal torsion-free connection and some of their solutions for the zero signature
On a 4-manifold of conformal torsion-free connection with zero signature (−−++) we found conditions under which the conformal curvature matrix is dual (self-dual or anti-self-dual). These conditions are 5 partial differential equations of the 2nd order on 10 coefficients of the angular metric and 4...
