Positive definite matrices play a central role in mathematics, physics, statistics and engineering due to their unique properties and widespread applicability. These matrices, which are characterised ...

Geometric statistics extends classical statistical methods to data that reside on curved spaces rather than flat Euclidean domains. At its core lies the notion of a manifold: a smooth, curved surface ...

Symmetric matrices of huge size with many zero entries, called sparse symmetric matrices, are nowadays studied actively in the context of artificial intelligence and data science. One of the efficient ...
