Characteristic Curves and the exponentiation in the Riordan Lie group: A connection through examples

Pedro J. Chocano, Ana Luzón, Manuel Alonso Morón +1

We point out how to use the classical characteristic method, that is used to solve quasilinear PDE's, to obtain the matrix exponential of some lower triangle infinite matrices. We…
