Abstract: We consider a condition on the Ricci curvature involving vector fields, which is broader than the Bakry-\'Emery Ricci condition. Under this condition volume comparison, Laplacian comparison, isoperimetric inequality and gradient bounds are proven on the… read more here.

Abstract: There are few intraday volume forecasting models in the literature, and they do not reflect on each other regarding forecast performance. This paper compares two models that are often referenced: the model of Bialkowski et… read more here.
