Junk solutions

Read Original

This article discusses the importance of non-polynomial solutions to differential equations that orthogonal polynomials satisfy. While these solutions are often overlooked, they are crucial for applications like Gaussian quadrature error analysis and are the minimal solution to the three-term recurrence. The author draws an analogy to 'junk' DNA, emphasizing that these solutions carry essential information. The post is a high-level introduction, promising future detailed posts.
