|Title:||A Characterization Of The Set Of Fixed Points Of Some Smoothed Operators|
De Pierro A.R.
|Abstract:||We characterize the set F of fixed points of an operator T(x) = SQ(x), where S is a positive definite, symmetric, and stochastic matrix and Q is a convex combination of orthogonal projections onto closed convex sets. We show that F is the set of minimizers of a convex function: the sum of a weighted average of the squares of the distances to the convex sets and a nonnegative quadratic related to the matrix S. © 1992.|
