A new paper out with my colleague Jorge Rivero. We approximate a real-valued step function with a matching pursuit (MP) algorithm, which utilizes a waveform dictionary with rectangular window functions. sciencedirect.com/science/articl… (researchgate.net/publication/36…)

We introduce an SDE for intraday copper futures prices, based on the whitening filter, a method characterizing linear time-variant systems. The predictability of copper futures prices is weak: the SDE performs well only in the short term MDPI mdpi.com/2227-9091/10/1…

I am happy to share our last preprint "Applications of Lax-Milgram theorem to problems in frame theory" with Laura De Carli arxiv.org/abs/2212.01102
