to the Euler stationary equations for ideal fluid, the speaker and his research group derive an infinite series of identities (orthogonality relations) that equate some linear combinations of mth degree integral momenta of the functions uiuj and p to zero (m = 0, 1, ... ). In particular, zeroth degree orthogonality relations are:
and
.
Orthogonality relations of degree m are valid for a solution
, where
is the weighted Sobolev space with the norm

About the speaker
Prof Vladimir Sharafutdinov obtained his PhD in Differential Geometry at Novosibirsk State University in 1974 and his Doctor of Sciences at Sobolev Institute of Mathematics in 1990. During 1973 – 1977, he was an Assistant Professor at the Novosibirsk State Pedagogical College. He then moved to the Novosibirsk State University in 1978 and is currently a Professor there. He is also the Leading Researcher at the Sobolev Institute of Mathematics in Novosibirsk.
Prof Sharafutdinov's research interests lie in Riemannian geometry, inverse problems and mathematical problems of tomography.
