Projected Normal Models on Recursively Curved Tori

Surojit Biswas, Aron Persson

We develop a computationally tractable statistical framework for angular data supported on a recursively embedded curved torus . Due to…

Extended Kalman Filtering on Stiefel Manifolds

Jordi-Lluís Figueras, Aron Persson, Lauri Viitasaari

A generalisation of the extended Kalman filter for Stiefel manifold-valued measurements is presented. We provide simulations on the 2-sphere and the space of orthogonal 4-by-2 matr…

On the Convergence of the Extended Kalman Filter on Stiefel Manifolds when Observing a Constant Particle with Measurement Errors

Jordi-Lluís Figueras, Aron Persson, Lauri Viitasaari

In this paper we first introduce the setting of filtering on Stiefel manifolds. Then, assuming the underlying system process is constant, the convergence of the extended Kalman fil…

Autoregressive Processes on Stiefel and Grassmann Manifolds

Jordi-Lluís Figueras, Aron Persson

System identification methods for autoregressive processes on Stiefel and Grassmann manifolds are presented and studied. We model the system parameters as elements of the orthogona…

On parameter estimation for based on projected data into

Jordi-Lluís Figueras, Aron Persson, Lauri Viitasaari

We consider the projected normal distribution, with isotropic variance, on the 2-sphere using intrinsic statistics. We show that in this case, the expectation commutes with the pro…

On manifold-like polyfolds as differential geometrical objects with applications in complex geometry

Per Åhag, Rafał Czyż, Håkan Samuelsson Kalm +1

We argue for more widespread use of manifold-like polyfolds (M-polyfolds) as differential geometric objects. M-polyfolds possess a distinct advantage over differentiable manifolds,…
