Variational principles provide a powerful and unifying framework to derive the governing equations of systems by optimising an action functional. Traditionally applied in classical mechanics via ...

Available to watch now, IUVSTA, in partnership with Agilent Technologies explores how magnetohydrodynamics can be formulated through a variational principle as a field theory In this webinar, ...

We prove existence and uniqueness results for patterns of circles with prescribed intersection angles on constant curvature surfaces. Our method is based on two new functionals--one for the Euclidean ...
