Schauder estimates for parabolic nondivergence operators of Hörmander type (2007, background): “uniformly in Ω or U (see [2] for (1.”
A Cortical Based Model of Perceptual Completion in the Roto-Translation Space (2006, methodology): “The expression of the fundamental solution is not known explicitly, but it can be approximated locally in time, with the parametrix method of Miranda (see [57], for the application of the method to general sub-Elliptic operators—see also [8]).”
Regularity of non-characteristic minimal graphs in the Heisenberg group $H^1$ (2008, background): “Precise estimates for the fundamental solution Γx0 have been established in [32] and [4], while in [15] it is proved that the fundamental solution Γε,x0 of Nε,x0 locally satisfies the same estimates as the limit kernel Γx0 , with choice of constants independent of ε.”
