A short open space curve of unit width
Tinko Sebastian Bartels, Dennis Kevin Choy, Ruixiang Wu +1
In this work, we propose a curve to be a minimum of length among rectifiable, continuous curves of unit width in three-dimensional Euclidean space. We show that a previously conjec…
Non-commutative law of rare events
Marco Tulio Gaxiola, Arturo Jaramillo
We establish quantitative versions of the law of rare events and binomial approximations in non-commutative probability settings, including the free, Boolean, and monotone convolut…
Robust Scale Estimation in Additive Noise via Weighted Order Statistics
