This study is driven by the wish to extend the previous theory to the fractional setting emphasizing the possible difference between the two type of operators due to the nonlocal attitude of the equations. Starting from the problem of unique continuation, many result have been achieved in the st...
whereas the former also rely on integral operators.Footnote1The integral form allows for the description of long-range interactions (spanning either small regions or the whole space) and reduces the regularity
The second line in Eq. (1) describes the effect of phonons. The operatorbj(†)annihilates (creates) a phonon on the sitej. The phonon operators are coupled to the electronic density operator defined as
free operators in Ginkgo solvers, new wrappers for Ginkgo preconditioners, HIP support, and reduction of unnecessary data copies. - Added initial support for hypre's mixed integer (mixedint) capability, which uses different data types for local and global indices in order to save memory in...
(\(\nu \)1)) are quite general, allowing for degenerate operators and no restrictions on the tail of the Lévy measure \(\nu \). There has been some development on numerical approximations for MFG systems with local operators. Finite difference schemes for nondegenerate second-order equations...
The annealed rate td/(d+α) is always governed by the exponent α appearing in (1.4), which in turn is determined by the behaviour of the exponent of ψ near zero. Formula (1.4) together with some mild assumptions concerning the behaviour of the symbol at infinity permit to obtain the ...
Furthermore, nonlocal perimeters and related fractional operators have been studied also from the numerical point of view, also due to their flexibility in image reconstruction theory, see e.g. [BS15, BBN+18, BLN19]. Hence, in general, the nonlocal perimeter functional provides a burgeoning ...
