with all the coefficients are fuzzy numbers. The FNE as follows, $$\begin{aligned} \begin{aligned}&{\tilde{a}}_{1}{\tilde{x}}^{3} + {\tilde{b}}_{1}{\tilde{x}}^{2 ...

Identifying governing equations from observational data is crucial for understanding nonlinear physical systems but remains challenging due to the risk of overfitting. Here we introduce the Bi-Level ...

After 10 years, Prof. Raimar Wulkenhaar from the University of Münster's Mathematical Institute and his colleague Dr. Erik Panzer from the University of Oxford have solved a mathematical equation ...

Non-linear physics is the study of systems where the output is not directly proportional to the input. Unlike linear systems, which follow simple, predictable relationships, non-linear systems exhibit ...
