We study interpolation polynomials based on the points in [âˆ’1, 1]Ã— [âˆ’1, 1] that are common zeros of quasi-orthogonal Chebyshev polynomials and nodes of near minimal degree cubature formula. With theâ€¦ (More)

BACKGROUND
Hippocampal atrophy--particularly of the CA1 region--may be useful as a biomarker for Alzheimer's disease (AD) or the risk for AD. The extent to which the AD hippocampus can beâ€¦ (More)

We give a simple, geometric and explicit construction of bivariate interpolation at certain points in a square (called Padua points), giving compact formulas for their fundamental Lagrangeâ€¦ (More)

As is well known the kernel of the orthogonal projector onto the polynomials of degree n in L2(wÎ±,Î² , [âˆ’1, 1]) with wÎ±,Î²(t) = (1âˆ’t) (1+t) can be written in terms of Jacobi polynomials. It is shownâ€¦ (More)
