    1 dzień temu · This norm makes it possible to define the distance d(p, q) ... For example, the last matrix representation given above corresponds to the multiplication table × a d ... Like functions of a complex variable, functions of a quaternion variable suggest useful physical models. For example, the original electric and magnetic fields described by ...

  2. 1 godzinę temu · Thus, we focus on the perturbation theory of TRS for the above three cases.The contributions of this work are as follows: First, suppose that the TRS is in easy case, we give a sufficient condition under which the perturbed TRS is still in easy case.Secondly, with the help of the structure of the matrix problem arising in TRS (), we perform first-order perturbation analysis on the Lagrange ...
