Wave extension problem for the fractional Laplacian
Mikko Kemppainen, Peter Sjögren, José Luis Torrea
We show that the fractional Laplacian can be viewed as a Dirichlet-to-Neumann map for a degenerate hyperbolic problem, namely, the wave equation with an additional diffusion term t…

On vector-valued tent spaces and Hardy spaces associated with non-negative self-adjoint operators
Mikko Kemppainen
In this paper we study Hardy spaces associated with non-negative self-adjoint operators and develop their vector-valued theory. The complex interpolation scales of vector-valued te…
