Lagrangian immersion

TīmeklisA Lagrangian immersion of a Riemannian n-manifold M into a Kahler n-manifold M is an isometric immersion such that the complex structure J of M interchanges each tangent space of M with its corresponding normal space. Lagrangian submanifolds appear naturally in classical mechanics and mathemat ical physics. Furthermore, … Tīmeklis2024. gada 12. apr. · This task is not trivial for the diffuse IBM because it uses a smoothed regularized delta function in the transfer steps between Lagrangian and Eulerian locations.
