Information
has gloss	eng: In theoretical physics, mysterious duality is a set of mathematical similarities between some objects and laws (and perhaps all of them, if the conjecture is extended appropriately) describing M-theory on k-dimensional tori (i.e. type II superstring theory on T^k-1} if k is positive) on one side, and geometry of del Pezzo surfaces (for example, the cubic surfaces) on the other side.
