On distributional solutions of local and nonlocal problems of porous medium type
(Journal article; Peer reviewed, 2017)We present a theory of well-posedness and a priori estimates for bounded distributional (or very weak) solutions of ∂tu − L σ,µ[ϕ(u)] = g(x, t) in R N (0.1) × (0, T ), where ϕ is merely continuous and nondecreasing and L ... -
Time-frequency analysis on the adeles over the rationals
(Journal article; Peer reviewed, 2019)We show that the construction of Gabor frames in with generators in and with respect to time-frequency shifts from a rectangular lattice is equivalent to the construction of certain Gabor frames for over the adeles over ...
