Scattered Data Interpolation Using C² Supersplines Of Degree Six

, 1995
. We show how C 2 supersplines of degree 6 can be used to interpolate Hermite data at the vertices of a quadrangulation. We also present error bounds which show that our method has full approximation order 7, and compare its efficiency with other C 2

Construction Techniques for Highly Accurate Quasi-Interpolation Operators

, 1996
: Under mild additional assumptions this paper constructs quasi-interpolants in the form f h (x) = +1 X j=\Gamma1 f(hj)' h i x h \Gamma j j ; x 2 IR; h ?

Multivariate Asymptotics for Products of Large Powers with Applications to Lagrange Inversion

, 1999
An asymptotic estimate is given for the coefficients of products of large powers of generating functions. This theorem and another local limit theorem which is useful for conditioning are applied to various combinatorial enumeration problems that involve

Biorthogonal Wavelet Expansions

This paper is concerned with developing conditions on a given finite collection of compactly supported algebraically linearly independent refinable functions that insure the existence of biorthogonal systems of refinable functions with similar properties.
