ESTIMATION OF A CONDITION NUMBER RELATED TO THE WEIGHTED DRAZIN INVERSE
Dijana Mosić · 2009
In this paper we get the formula for the condition number of the W-weighted Drazin inverse solution of a linear system WAWx = b, where A is a bounded linear operator between Hilbert spaces X and Y , W is a bounded linear operator between Hilbert spaces Y and X, x is an unknown vector in the range of (AW) D and b is a vector in the range of (WA) D.
