Obviously, φ(s, x, t) has continuous partial derivatives ∂∂sφ(s,x,t),∂∂xφ(s,x,t) and ∂2∂x2φ(s,x,t) , and therefore it can be approximated by the first two terms of the Taylor expansion in the neighborhood of the point x (under a fixed u and t): φ(...

Let (Z,W)=g(X,Y)=(g1(X,Y),g2(X,Y))(Z,W)=g(X,Y)=(g1(X,Y),g2(X,Y)), where g:R2↦R2g:R2↦R2 is a continuous one-to-one (invertible) function with continuous partial derivatives. Let h=g−1h=g−1, i.e., (X,Y)=h(Z,W)=(h1(Z,W),h2(Z,W))(X,...
Motivated by strong versions of Green's theorem, we give an example of a differentiable vector field for which the curl is continuous but not all the partial derivatives are continuous.doi:10.1080/00029890.2020.1815476Adam CoffmanYuan Zhang

We denote by Wk,p(Ω,ω) the set of all functions u∈Lp(Ω,ω0) for which the weak derivatives Dαu, with |α|≤k, belong to Lp(Ω,ωα). The weighted Sobolev space Wk,p(Ω,ω) is a normed linear space if equipped with the norm ‖u‖Wk,p(Ω,ω)=(∑|α|≤k∫Ω|D...
