Well-Conditioned Polynomial Representations for Mathematical Handwriting Recognition
Robert M. Corless, Deepak Singh Kalhan, Stephen M. Watt
Previous work has made use of a parameterized plane curve polynomial representation for mathematical handwriting, with the polynomials represented in a Legendre or Legendre-Sobolev…
Structured Backward Error for the WKB method
Robert M. Corless, Nicolas Fillion
The classical WKB method (also known as the WKBJ method, the LG method, or the phase integral method) for solving singularly perturbed linear differential equations has never, as f…
Elliptic cross sections in blood flow regulation
Chris Brimacombe, Robert M. Corless, Mair Zamir
Arterial deformations arise in blood flow when surrounding tissue invades the space available for a blood vessel to maintain its circular cross section, the most immediate effects…
Perturbation Theory
Nicolas Fillion, Robert M. Corless
This article aims to explain essential elements of perturbation theory and their conceptual underpinnings. It is not meant as a summary of popular perturbation methods, though some…
