T-duality is a particular example of a general notion of duality in physics. The term duality refers to a situation where two seemingly different physical systems turn out to be equivalent in a nontrivial way. If two theories are related by a duality, it means that one theory can be transformed in some way so that it ends up looking just like the other theory. The two theories are then said to be dual to one another under the transformation. Put differently, the two theories are mathematically diff… WebIn mathematics, the representation theory of the symmetric group is a particular case of the representation theory of finite groups, for which a concrete and detailed theory can be …

Since 4 = 1, a character ˜of Ghas ˜()4 = 1, so ˜takes only four possible values at , namely 1, 1, i, or i. Once ˜() is known, the value of ˜elsewhere is determined by multiplicativity ...

They are expressions of the form a + bε, where a and b are real numbers, and ε is a symbol taken to satisfy with . Dual numbers can be added component-wise, and multiplied by the formula which follows from the property ε = 0 and the fact that multiplication is a bilinear operation.
