A generalization of Euler's constant
: The purpose of this paper is to evaluate the limit γ(a) of the sequence 1 a + 1 a + 1 + · · · + 1 a + n − 1 − ln a + n − 1 a n∈N , where a ∈ (0, +∞). We give some...

Conjectured inequalities for Jacobi polynomials and their largest zeros
Inequalities are conjectured for the Jacobi polynomials P (α,β) n and their largest zeros. Special attention is given to the cases β = α − 1 and β = α. Key words. Jacobi po...

Multivariate polynomial interpolation: conjectures concerning GC-sets
GC-sets are subsets T of Rd of cardinality dim Πn for which, for each τ ∈ T, there are n hyperplanes whose union contains all of T except for τ, thus making interpolation to a...

UPML formulation for truncating conductive media in curvilinear coordinates
Abstract. This work presents a formulation based on UPML for truncating conductive media by using a local and non-orthogonal coordinate system to solve Maxwell’s Equations by the...
