of first order differential equations as a initial value problem ω i (0)∈ℝ. The analysis is based on its quadratic first integrals C ij = α i ω j (υ) 2 - α j ω i (υ) 2. When N = 3 this system ...

For Gaussian quadrature rules over a finite interval, applied to analytic or meromorphic functions, we develop error bounds from contour integral representations of ...
