A Julia package for manipulating data in the Riemannian Manifold of Positive Definite Matrices
Show Knutson Tao Puzzles for spectra of sums of Hermitian Matrices
Demonstrates the emergence of a multifractal Non-Ergodic Extended (NEE) phase in arithmetic quantum chaos. Uses a Riemann-von Mangoldt scaffold and a Z/6Z modular PRBM mask to generate sub-diffusive spectral dynamics strictly bounded by Euler's totient fraction.
Software for computing the inertia of a hermitian Toeplitz-block matrix.
Python code that solves the eigensystem associated with Hermitan matrices. Demonstrated by finding the the first few eigenvalues and the corresponding eigenvectors of the aharmonic oscillator Hamiltonian.
P' L D L' P factorization of symmetric real or hermitian indefinite matrices
