Description
When numerically approximating a PDE on the line, it is common practice to replace the line by a large circle. At least for short times, this seems like a reasonable substitution, but how reasonable is it really? In this talk, I will address this question for the Benjamin–Ono equation, whose integrable structure leads to quantitative answers. This is ongoing joint work with Yvonne Alama-Bronsard.
