Diagonal-norm upwind SBP operators
I will present some new results concerning explicit high-order finite difference methods applied to hyperbolic systems. In particular I will present some new results that support the addition of appropriate artificial dissipation, even for linear problems. Recently, high-order accurate first derivative finite difference operators are were derived that naturally introduce artificial dissipation....
متن کاملDiagonal Operators and Bernstein Pairs
Replacing the nested sequence of ""nite" dimensional subspaces by the nested sequence of "closed" subspaces in the classical Bernstein lethargy theorem, we obtain a version of this theorem for the space B(X; Y) of all bounded linear maps. Using this result and some properties of diagonal operators, we investigate conditions under which a suitable pair of Banach spaces form an exact Bernstein pa...
متن کاملOptimal diagonal-norm SBP operators
Optimal boundary closures are derived for first derivative, finite difference operators of order 2, 4, 6 and 8. The closures are based on a diagonal-norm summation-by-parts (SBP) framework, thereby guaranteeing linear stability on piecewise curvilinear multi-block grids and entropy stability for nonlinear equations that support a convex extension. The new closures are developed by enriching con...
متن کاملResolvents of R-diagonal Operators
We consider the resolvent (λ−a)−1 of any R-diagonal operator a in a II1-factor. Our main theorem (Theorem 1.1) gives a universal asymptotic formula for the norm of such a resolvent. En route to its proof, we calculate the R-transform of the operator |λ− c|2 where c is Voiculescu’s circular operator, and we give an asymptotic formula for the negative moments of |λ − a|2 for any R-diagonal a. We ...
