Beyond Eigenspaces: Real Invariant Planes
Linear Algebra: In the context of real vector spaces, one often needs to work with complex eigenvalues. Let A be a real nxn matrix A. We show that, in R^n, there exists at least one of: an (nonzero) eigenvector for A, or a 2-dimensional subspace (plane) invariant under A.

Beyond Eigenspaces 2: Complex Form
Linear Algebra: As an application of the Spectral Theorem for real vector spaces, we show that every 2x2 matrix with no real eigenvalues can be represented as [x -y / y x] for some basis. This representation reflects common algebraic properties of the complex numbers.

Solving Systems of Differential Equations with Eigenvalues and Eigenvectors
We now show how to solve a generic matrix system of linear ordinary differential equations (ODEs) using eigenvalues and eigenvectors. This is one of the most powerful techniques in linear systems theory, with applications in stability theory and control. Code examples are given in Pyt

Cyclic homology and S1S1-equivariant symplectic cohomology - Sheel Ganatra
Sheel Ganatra Stanford University November 21, 2014 In this talk, we study two natural circle actions in Floer theory, one on symplectic cohomology and one on the Hochschild homology of the Fukaya category. We show that the geometric open-closed string map between these two complexes is S

Angélica M. Osorno - Equivariant Infinite Loop Space Machines
An equivariant infinite loop space machine is a functor that constructs genuine equivariant spectra out of simpler categorical or space level data. In the late 80’s Lewis–May–Steinberger and Shimakawa developed generalizations of the operadic approach and the G-space approach respectively.
