IMPROVED REGULARITY OF SECOND DERIVATIVES FOR SUBHARMONIC FUNCTIONS
Xavier Fernandez-Real Girona, Riccardo Tione
In this note, we prove that if a subharmonic function Delta u >= 0 has pure second derivatives partial derivative(ii)u that are signed measures, then their negative part (partial derivative(ii)u)- belongs to L-1 (in particular, it is not singular). We then ...
Providence2023On a Finite-Size Neuronal Population Equation
Tilo Schwalger, Valentin Marc Schmutz, Eva Löcherbach
Population equations for infinitely large networks of spiking neurons have a long tradition in theoret-ical neuroscience. In this work, we analyze a recent generalization of these equations to populations of finite size, which takes the form of a nonlinear ...
SIAM PUBLICATIONS2023Coordinate Difference Matrices
Martin Vetterli, Gilles Baechler, Miranda Krekovic, Golnooshsadat Elhami
In many problems such as phase retrieval, molecular biology, source localization, and sensor array calibration, one can measure vector differences between pairs of points and attempt to recover the position of these points; this class of problems is called ...
