%0 Journal Article %T Superalgebras in Many Types of M-Brane Backgrounds and Various Supersymmetric Brane Configurations %A Takeshi Sato %J Physics %D 1998 %I arXiv %R 10.1016/S0550-3213(99)00123-6 %X We derive superalgebras in many types of supersymmetric M-brane backgrounds. The backgrounds examined here include the cases of the M-wave and the M-Kaluza-Klein monopole. On the basis of the obtained algebras, we deduce all the supersymmetric non-orthogonal intersections of the M-Kaluza-Klein monopole and the M-5-brane at angles. In addition, we present a 1/4 supersymmetric worldvolume 3-brane soliton on the M-5-brane in the M-5-brane background as an extended solution of the 3-brane solitons of the M-5-brane by Howe, Lambert and West. This soliton can be interpreted as a certain intersection of three M-5-branes. %U http://arxiv.org/abs/hep-th/9812014v4
