p-brane solutions and Beltrami-Laplace operator
arXiv:hep-th/9710110
Abstract
Generalization of harmonic superposition rule for the case of dependent choice of harmonic functions is given. Dependence of harmonic functions from all (relative and overall) transverse coordinates is considered using the Beltrami-Laplace operator. Supersymmetry of IIB 10D supergravity solutions with only non-vanished 5-form field and 11D supergravity solutions is discussed.
