Interpolation polynomials of entire functions for Erdős-type weights (Q355713)

Summary: Let \(\mathbb R = (-\infty, \infty)\), and let \(Q \in C^1(\mathbb R) : \mathbb R \to [0, \infty)\) be an even function. We consider some Lagrange interpolation polynomials and the Gauss-Jacobi quadrature formula of entire functions associated with Erdős-type weights \(w(x) = e^{-Q(x)}\), \(x \in \mathbb R\), and we will estimate the error terms.
