On Convergence and Degeneracy in Rational Padi and Chebyshev Approximation *
We study two questions associated with rational approximation of a function f(z) near the origin z-0: continuity of the Pad approximation operator, and convergence of Chebyshev to Pad ap-proximants as the domain of approximation shrinks to a point. Both become delicate in the case of degenerate approximations, i.e. approximations whose numerator and denominator are deficient in degree. In this ...
متن کاملNonlinear approximation
This is a survey of nonlinear approximation, especially that part of the subject which is important in numerical computation. Nonlinear approximation means that the approximants do not come from linear spaces but rather from nonlinear manifolds. The central question to be studied is what, if any, are the advantages of nonlinear approximation over the simpler, more established, linear methods. T...

متن کاملProperties of Nuclear and Neutron Matter and Thermodynamic Consistency in a Nonlinear Mean-field Approximation
Properties of nuclear and neutron matter are discussed in a nonlinear σ-ω-ρ mean-field approximation with self-interactions and mixing-interactions of mesons and baryons. The nonlinear interactions are renormalized by employing the theory of conserving approximations, which results in a thermodynamically consistent approximation that maintains Hugenholtz-Van Hove theorem and Landau’s requiremen...
متن کاملSampling and nonlinear approximation of band limited signals in mean oscillation spaces
| This paper deals with the nonlin-ear approximation of band limited signals using their sampled values on an appropriate discrete set. Some spaces of sequences introduced by the author in previous work are used to measure the oscillation of such signals. These spaces can be viewed as discrete versions of Sobolev or, more generally, Beosv spaces. A discrete wavelet type characterization of sign...
