Very Weak Space-Time Variational Formulation for the Wave Equation: Analysis and Efficient Numerical Solution

Julian Henning, Davide Palitta, Valeria Simoncini +1

We introduce a very weak space-time variational formulation for the wave equation, prove its well-posedness (even in the case of minimal regularity) and optimal inf-sup stability.…

Linear/Ridge expansions: Enhancing linear approximations by ridge functions

Constantin Greif, Philipp Junk, Karsten Urban

We consider approximations formed by the sum of a linear combination of given functions enhanced by ridge functions -- a Linear/Ridge expansion. For an explicitly or implicitly giv…
