In this section, we compute Bott-Chern cohomology for compact complex surfaces in class \text {VII}. Let X be a compact complex surface. By Theorem 1.1, the natural map H^ {2,1}_ {BC} (X) \rightarrow H^ {2,1}_ {\overline {\partial }} (X) is always injective. Consider now the case when X is in class \text {VII}.

WebUsing G2(2) dualities we construct the most general black string solution of minimal five-dimensional ungauged supergravity. The black string has five independent parameters, namely, the magnetic one-brane charge, smeared electric zero-brane charge, boost along the string direction, energy above the BPS bound, and rotation in the transverse space.
