Abstract Let 𝜉 = {𝜉𝑛}𝑛≥₀ be a Markov chain defined on a probability space (Ω, ℱ, ℙ) valued in a discrete topological space 𝑆 that consists of a finite number of real 𝑑 × 𝑑 matrices. As usual, ...
The equiangular spiral is an example of a simple but fascinating scalar exponential function. The author explains how the scalar exponential can be extended to the multidimensional matrix case to ...
