WebOuter Products and Tensor Products. Inner products aren't the only way to multiply vectors. Occasionally, we'll switch the order of the bra and ket in order to take the outer product, whose outcome is a matrix, rather than a single number. For two vectors $ a\rangle$ and $ b\rangle$ in a Hilbert space, we denote the outer product as $ a ... WebFor any reflection transformation surely there are infinite eigenvalues, because all of the vectors along the line of reflection would not be changed, nor would those orthogonal to …
