Nonlinear Approximation and the Space BV(R)
Given a function f 2 L2(Q), Q := [0; 1) and a real number t > 0, let U(f; t) := infg2BV(Q) kf gk 2 L2(I) + tVQ(g); where the in mum is taken over all functions g 2 BV of bounded variation on I. This and related extremal problems arise in several areas of mathematics such as interpolation of operators and statistical estimation, as well as in digital image processing. Techniques for nding minimi...
