     要It is well known that an element of CP^1 is visualized by a point in S^2. Roughly sepaking, it means a two-dimensional complext vector, when the overall U(1) factor is ignored as is done in quantum mechanics, can be regarded as a point in S^2. Then it is natural to ask what is the correspoinding visualization for a vector in C^d with d>2. The Majorana representation visualizes a vector in C^d in terms of d-1 points, called the Majorana vectors, in S^2. This is based on the observation that a vector in C^d is represented as a symmetrized tensor product of d-1 C^2 vectors.In my seminar, I introduce how to obtain the Majorana representation and some of its applications to combinatorics and cold atom physics.
