If A is a symmetric matrix, then A = A T and if A is a skew-symmetric matrix then A T = - A. The Hilbert matrix can be regarded as derived from the integral = +, that is, as a Gramian matrix for powers of x.It arises in the least squares var - (optional, default: 'a') variable used to represent generator of the finite field, if needed. From the perspective of Sen entropy function, we study the geometric and algebraic properties of a class of (extremal) black holes in D4 spacetimes. But the difference between them is, the symmetric matrix is equal to its transpose whereas skew-symmetric matrix is a matrix whose transpose is equal to its negative. For instance , it is the key to the definition of the metaplectic group [50, 26]. Then by defining an orthogonally multi-symplectic matrix P (S) = P 1 (S) P 2 (S), we have (P (S)) T A P (S) of the form , in which D j (t), R j (t) . .

At this stage it appears that the usage of the symplectic systems theory for the control Symmetric Matrix. I know the matrices representing the PB and the symplectic form are inverse to one another, the problem lies on their representation, i.e., in the (q,p) representation w^{ij} have to be the matrix elements of the symplectic matrix so we get the right expression for the PB (if the order of the \xi are q1,q2,p1,p2, for example). my intuition is to found some legality or somthing like that, and to use it to get a simple solution.
