SIAM Journal on Numerical Analysis, Vol. 36, No. 4 (May - Jun., 1999), pp. 1183-1233 (51 pages) We use biorthogonal filter banks to solve hyperbolic PDEs adaptively with a sparse multilevel ...

Most educational platforms feature a core trait such as learning, discussing or problem solving. Function Space, a social learning science network, wants to bring the three together for free in a ...

We prove that if two level curves of a harmonic function are convex in the hyperbolic disc then all intermediate level curves are also convex. This item is part of a ...

Rapidly-varying free-surface flows are characterized by large surface gradients. These flows can be found for example, in hydraulic jumps, tsunamis, tidal bores and releases from power stations. Large ...
