Particle Spreading in a Simple Majda Flow and Eigenvalue Estimation Through a Cayley Transform
… We consider a perturbation method based on a Cayley transform. We show that the change of basis V = (I + K/2)-1( I - K/2), where I is the identity operator and K is a skew-adjoint operator given by a formal perturbation argument, gives better error estimate.

Constrained Optimization on SO(3), via Pseudospectral Collocation
… to the tangent space through equivariant transformations, with the Cayley map providing a computationally efficient coordinate representation. The resulting discretized system is then formulated within a Riemannian optimization framework, ensuring geometric consistency. This work …

Coherent versus non-coherent space-time shift keying for co-located and distributed MIMO systems
… philosophy is conceived with the aid of the Cayley transform and differential unitary space-time modulation. The DSTSK receiver benefits from low-complexity non-coherent single-streambased ML detection, while retaining the CSTSK scheme’s fundamental benefits. In order to create further …

Analytic and Numerical aspects of isospectral flows
In this thesis we address the analytic and numerical aspects of isospectral flows. Such flows occur in mathematical physics and numerical linear algebra. Their main structural feature is to retain the eigenvalues in the solution space. We explore the solution of Isospectral flows and their …
