Freudenthal对偶与广义特殊几何

Freudenthal Duality and Generalized Special Geometry

Sergio Ferrara, Alessio Marrani, Armen Yeranyan

摘要:

Freudenthal对偶性是L. Borsten,D. Dahanayake,M. J. Duff和W. Rubens,Phys.Rev. D80,026003(2009),定义为d = 4维时空中对子电荷矢量的反对合,证明了它不仅是经典Bekenstein-Hawking熵的对称性,而且也是黑洞势临界点的对称性。此外,弗赖登塔尔对偶被推广到任何广义特殊几何,因此包含所有N > 2的超引力,以及N = 2的一般特殊几何,不一定有陪集空间结构。

英文摘要:

Freudenthal duality, introduced in L. Borsten, D. Dahanayake, M. J. Duff and W. Rubens, Phys.Rev. D80, 026003 (2009), and defined as an anti-involution on the dyonic charge vector in d = 4 space-time dimensions for those dualities admitting a quartic invariant, is proved to be a symmetry not only of the classical Bekenstein-Hawking entropy but also of the critical points of the black hole potential. Furthermore, Freudenthal duality is extended to any generalized special geometry, thus encompassing all N > 2 supergravities, as well as N = 2 generic special geometry, not necessarily having a coset space structure.
