We prove the existence of three-dimensional steady gravity-capillary waves with vorticity on water of finite depth. The waves are periodic with respect to a given two-dimensional lattice and the relative velocity field is a Beltrami field, meaning that the vorticity is collinear to the velocity. The existence theory is based on multi-parameter bifurcation theory.
ELT science drivers stress aperture, Strehl ratio, PSF definition andstability, field of view, wavelength range, flexibility, lowpolarisation and thermal emittance, auxiliary instruments, site andinfrastructure. Applicable science categories are planets and planetarysystems, stars and stellar systems, galaxies and galaxy clusters, andcosmology. ELT observations are needed for our own and other pla
The frame story
takes place in a dystopian Europe, possibly some kind of European Union around 2050 – in a state of conflicts and decay. The protagonists are a retired general, Piscator (cf. Fisher King) and a former journalist, Perle Vaus (cf. Perlesvaus/Perceval/Parsifal). She lost her home because of a new genderrelated law and stays homeless with others, covered by the Saxon bridge.
