Compact Central WENO Schemes for MultiDimensional Conservation Laws

2015/10/8
We present a new third-order central scheme for approximating solutions of systems of conservation laws in one and two space dimensions. In the spirit of Godunov-type schemes, our method is based on r...
Necessary conditions for variational regularization schemes
Variational regularization Tikhonov regularization necessary conditions general discrepancy term Bregman distances

We study variational regularization methods in a general framework, more precisely those methods that use a discrepancy and a regularization functional. While several sets of sufficient conditions are...
Exchange between perverse and weight filtration for the Hilbert schemes of points of two surfaces
Exchange perverse weight filtration Hilbert schemes points of two surfaces

We show that a natural isomorphism between the rational cohomology groups of the two zero-dimensional Hilbert schemes of n-points of two surfaces, the affine plane minus the axes and the cotangent bun...

Given a finite subgroup SL2(C) we define an additive 2-category H whose Grothendieck
group is isomorphic to an integral form h of the Heisenberg algebra. We construct...
