Hace 5 días · With Brian Greene, Alfred Shapere, and Cumrun Vafa, Yau introduced an ansatz for a Kähler metric on the set of regular points of certain surjective holomorphic maps, with Ricci curvature approximately zero. They were able to apply the Tian−Yau existence theorem to construct a Kähler metric which is exactly Ricci-flat.
Hace 1 día · In a quantum theory of gravity, the species scale Λs can be defined as the scale at which corrections to the Einstein action become important or alternatively as codifying the “number of light degrees of freedom”, due to the fact that Λ s − 1 $$ {\\Lambda}_s^{-1} $$ is the smallest size black hole described by the EFT involving only the Einstein term. In this paper, we check the ...

Hace 4 días · Inzwischen aber (etwa 2010) gilt als M-Theorie eher, was heute der Schwerpunkt aller Bemühungen um die Stringtheorie ist: Jede widerspruchsfreie Quantentheorie, die die 11-dimensionale Supergravitation als niederenergetischen Grenzfall umfasst. [Steven Gubser, ein junger Stringtheoretiker, sagt uns das auf Seite 65 seines Buches Das kleine ...
