Lie Algebra
In this article, I will introduce Lie algebra, which essentially is related to the Poisson brackets we studied before. Definition Lie AlgebraFor a vector space #mjx-f7e6eb3{ ...
From the θ-Scheme to the Stokes Saddle-Point System
Why a matrix formulation in the first place We want to solve the instationary Stokes equations, but a PDE that carries a time derivative cannot be handed to a stationary linear solver directly. The...
Poisson Brackets
The whole of mechanics can be summarized in a single bracket. — paraphrasing the spirit of Hamilton and Jacobi. In classical mechanics every observable lives on the phase space, the space of state...
Intuitions and Speculations on Variational Formulation
Solving a Linear System We begin with a deceptively simple question that every undergraduate student encounters in their first linear algebra course: solving the linear system #m...
