Avoiding discretization issues for nonlinear eigenvalue problems
MJ Colbrook, A Townsend - arXiv preprint arXiv:2305.01691, 2023 - arxiv.org
The first step when solving an infinite-dimensional eigenvalue problem is often to discretize
it. We show that one must be extremely careful when discretizing nonlinear eigenvalue …

Hydrodynamics of a twisting, bending, inextensible fiber in Stokes flow
In swimming microorganisms and the cell cytoskeleton, inextensible fibers resist bending
and twisting, and interact with the surrounding fluid to cause or resist large-scale fluid …

A high-order fast direct solver for surface PDEs
D Fortunato - SIAM Journal on Scientific Computing, 2024 - SIAM
We introduce a fast direct solver for variable-coefficient elliptic PDEs on surfaces based on
the hierarchical Poincaré–Steklov method. The method takes as input an unstructured, high …

[图书][B] Exploring ODEs
What if all you had to do to solve an ODE were just to write it down? 1 That is the line we will
follow in this book. Our emphasis is not just on the mathematics of ODEs, but on how the …
