A smoothness/shock indicator for the RKDG methods
A smoothness/shock indicator is proposed for the RKDG methods solving nonlinear conservation laws. A few numerical experiments are presented as evidence that the indicator helps in...

Solutions to stochastic fractional oscillation equations
We formulate a fractional stochastic oscillation equation as a generalization of Bagley's fractional differential equation. We do this in analogous way as in the case of Bass...

A note on single-linkage equivalence
We introduce the concept of single-linkage equivalence of edge-weighted graphs, we apply it to characterise maximal spanning trees and "ultrasimilarities", and we discus...

A variational principle for doubly nonlinear evolution
The weighted energy-dissipation principle stands as a novel variational tool for the study of dissipative evolution and has been already applied to rate-independent systems and gra...

Computing Fourier transforms and convolutions of Sn-1-invariant signals on Sn in time linear in n
Let Sn denote the symmetric group on {1, . . . , n} and Sn-1 the stabilizer subgroup of n. We derive algorithms for computing Fourier transforms of left and right Sn-1-invariant s...
