DESCRIPTION:In a joint work with Laszlo Szekelyhidi we constru
ct continuous weak solutions of the 3d incompressi
ble Euler equations\, which dissipate the total ki
netic\nenergy. The construction is based on the sc
heme introduced by J. Nash for producing C1 isomet
ric embeddings\, which was later developed by M.Gr
omov\ninto what became known as convex integration
. Weak versions of convex integration (e.g. based
on the Baire category theorem) have been used prev
iously\nto construct bounded (but highly discontin
uous) weak solutions. The current construction is
the first instance of Nash's scheme being applied
to a PDE which one might classify as "hard" as opp
osed to "soft".
