Nonlinear evolution equations that are non-local in space and time

We deal with a nonlocal nonlinear evolution problem of the form ∬Rn×RJ(x−y,t−s)|v‾(y,s)−v(x,t)|p−2(v‾(y,s)−v(x,t))dyds=0 for (x,t)∈Rn×[0,∞). Here p≥2, J:Rn+1→R is a nonnegative kernel, compactly supported inside the set {(x,t)∈Rn+1:t≥0} with ∬Rn×RJ(x,t)dxdt=1 and v‾ stands for an extension of a give...
