Nonlocal tangent operator for damage plasticity model
This paper deals with the computational analysis of the nonlocal damage-plastic model. The return mapping algorithm based on the closest-point projection is developed and the corresponding consistent algorithmic stiffness is derived. The pro...

F-transform Representation of Nonlocal Operators with Applications to Image Restoration
In nonlocal operators, nonlocal operators define a new type of functionals that extend the ability of classical PDE-based algorithms in handling textures propose a new total variation model with the F-transform-b...

On nonlocal symmetries for the Krichever-Novikov equation
We construct new infinite hierarchies of nonlocal symmetries and cosymmetries for the Krichever-Novikov equation using the inverse of the fourth-order recursion operator of the latter....

Nonlocal symmetries, conservation laws, and recursion operators of the Veronese web equation
of nonlocal conservation laws. In the infinite differential coverings associated to these series, we describe the Lie algebras of the corresponding nonlocal symmetries. Finally, we construct a recursion operator and explor...

Why nonlocal recursion operators produce local symmetries: new results and applications
while the recursion operators that generate these hierarchies usually contain nonlocal terms. We resolve this apparent discrepancy by providing simple and universal sufficient conditions for a (nonlocal) recursion oper...
