WebThe derivatives with respect to order {\nu} for the Bessel functions of argument x (real or complex) are studied. Representations are derived in terms of integrals that involve the products pairs of Bessel functions, and in turn series expansions are obtained for these integrals. From the new integral representations, asymptotic approximations involving … Web4.2. MATRIX NORMS 219 Moreover, if A is an m × n matrix and B is an n × m matrix, it is not hard to show that tr(AB)=tr(BA). We also review eigenvalues and eigenvectors. We con-tent ourselves with definition involving matrices. A more general treatment will be given later on (see Chapter 8). Definition 4.4. Given any square matrix A ∈ M n(C),
