A local refinement strategy for constructive quantization of scalar SDEs

T Müller-Gronbach, K Ritter - Foundations of Computational Mathematics, 2013 - Springer
We present a fully constructive method for quantization of the solution X of a scalar SDE in

On mm-Entropy of a Banach Space with Gaussian Measure

AM Vershik, MA Lifshits - Theory of Probability & Its Applications, 2023 - SIAM
For a broad class of Banach spaces with Gaussian measure, we show that their entropy in
the sense of Shannon (the mm-entropy) is closely related to the entropy of the …
