The N-body problem, central to celestial mechanics and dynamical systems, explores the evolution and interaction of N objects under mutual forces—typically gravitational. Over decades, it has inspired ...

Fluid dynamics remains a cornerstone of applied mathematics and engineering, exploring the motion of fluids and the forces acting upon them. Central to this field is the concept of weak ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...
