S-膜解的T-对偶与降维

T-duality and dimensional reduction of S-brane solutions

Riuji Mochizuki, Kenji Ikegami

摘要:

本文研究了10维和11维超引力类空膜解的降维和T-对偶性,包括波解和波解的类空对应物。降维是定义良好的,当且仅当解具有静态维数。然而,T-对偶是不好定义的一些这些解决方案,其中的期望值依赖于时间。这使我们得出结论,只有当介子期望值与时间无关时,超引力解才应该被视为超弦理论的低能解。

英文摘要:

We studied dimensional reduction and T-duality in spacelike brane solutions of 10 or 11 dimensional supergravity, including spacelike counterparts of wave and monopole solutions. Dimensional reduction is well-defined if, and only if, the solutions possess static dimensions. However, T-duality is ill-defined for some of these solutions where dilaton expectation values depend on time. This led us to conclude that supergravity solutions should be regarded as low-energy solutions of superstring theory only if dilaton expectation values are independent of time.
