Suppose that the (not identically zero) linear operator A, on a real Hubert space H to itself, is compact, selfadjoint, and positive semidefinite; that y is a vector of H which is perpendicular to… (More)

The problem of simultaneous Chebyshev approximation of a set F of uniformly bounded, real-valued functions on a compact interval / by a set P of continuous functions is equivalent to the problem of… (More)
