V. D. Ivashchuk, V. N. Melnikov

摘要:

考虑一个含有标量场和反对称形式的多维引力模型。流形选择为M = M_0 x M_1 x. x M_n,其中M_i是Einstein空间(i > 0). sigma模型方法和交叉复合膜的精确解(例如,考虑了非奇异Kac-Moody(KM)代数(如双曲型)的交规则.给出了一些黑膜解的例子,例如,对应于双曲KM代数H_2(q,q)(q > 2),HA_2^(1)= A_2^{++}和Lorentz KM代数P_{10}的那些。

英文摘要:

A multidimensional gravitational model containing scalar fields and antisymmetric forms is considered. The manifold is chosen in the form M = M_0 x M_1 x ... x M_n, where M_i are Einstein spaces (i > 0). The sigma-model approach and exact solutions with intersecting composite branes (e.g., solutions with harmonic functions and black brane ones) with intersection rules related to non-singular Kac-Moody (KM) algebras (e.g. hyperbolic ones) are considered. Some examples of black brane solutions are presented, e.g., those corresponding to hyperbolic KM algebras: H_2(q,q) (q > 2), HA_2^(1) = A_2^{++} and to the Lorentzian KM algebra P_{10}.
