👉 Sturmian is a term used in mathematics to describe a function that is both periodic and oscillatory. It is named after the mathematician Karl Wilhelm Sturm, who developed it in 1896. In the context of mathematical analysis, a function with these properties can be described as sturmian if its Fourier transform has a simple period (i.e., no zeros or poles) and an exponential decay at infinity. This type of function is often used to model oscillatory phenomena like
