In this study, we investigate a scenario by which the ice shelf of a major ice stream is progressively removed due to climate warming, and the ice stream response to the disparition of the ice shelf, that is disparition of the ice-shelf back stress.
Constructive proofs and several generalizations of approximation results of J. H. Bramble and S. R. Hilbert are presented. Using an averaged Taylor series, we represent a function as a polynomial plus a remainder. The remainder can be manipulated in many ways to give different types of bounds. Approximation of functions in fractional order Sobolev spaces is treated as well as the usual integer order spaces and several nonstandard Sobolev-like spaces.
