Resumen:
Under certain conditions, we prove that the Moore-Penrose inverse ofa sum of operators is the sum of the Moore-Penrose inverses. Fromthis, we derive expressions and characterizations for theMoore-Penrose inverse of an operator that are useful for itscomputation. We give formulations of them for finite matrices andstudy the Moore-Penrose inverse of circulant matrices and ofdistance matrices of certain graphs.
