Please help with this multivariable calculus problem in manifold!
Show that the set U(n) of unitary n x n - matrices (those n x n - matrices A with entries in complex number such that BTA=the identity matrix, where B is the matrix with entries the complex conjugates of those of A, i.e. if the 1st row and 1st column entry of A is i, then the 1st row and 1st column entry of B is -i) is a manifod. What is its dimension?
