Mathematical question (symmetry)

The state [uud] is given. The transposition (12) is a symmetry of this state e.g. (12)[uud]=[uud] Let us calculate the result under acting of the cycle (132): (132)[uud]=[duu] But (132)=(23)(12),...

Matrix based scientific data analysis: extrapolating to matrices of sets?

Data sets, when structured, can be put in vector form (v(1)...v(n)), adding time dependency it's v(i, t) for i=1...n and t=1...T. Then we have a matrix of terms v(i, j)... Matrices are important,...
