Drazin inverse based numerical methods for singular linear differential systems

[EN] In this paper, numerical methods for the solution of linear singular differential system are analyzed. The numerical solution of initial value problem by means of a corresponding finite difference approach and a possible implementation of the product Drazin inverse by vector is discussed. Examples of index-1 and index-2 DAEs have been studied numerically.This paper was partially supported by Grant GS1 DGI MTM2010-18228, by Ministry of Education of Argentina (PPUA, grant Resol. 228, SPU, 14-15-222) and by Universidad Nacional de La Pampa, Facultad de Ingenieria (grant Resol.
