Let X be a complex toric Fano n-fold and N (T ) the normalizer of a maximal torus T in the group of biholomorphic authomorphisms Aut(X). We call X symmetric if the trivial character is a single N (T… (More)

H = ρ0(r, B1, B2)(r dφ + dr)− ρ1(r)(B1 sin 2φ+B2 cos 2φ)− ρ2(r) cosφ (2) where B1, B2 are constants and ρ0, ρ1, ρ2 are some functions. It has been shown in [5] that this family reduced to the case of… (More)

The aim of this paper is to describe a class of conservative systems on S possessing an integral cubic in momenta. We prove that this class of systems consists off the case of Goryachev-Chaplygin,… (More)

It has been proved that on 2-dimensional orientable compact manifolds of genus g > 1 there is no integrable geodesic flow with an integral polynomial in momenta, see [5, 6]. There is a conjecture… (More)

In 2002, the neritic copepod Acartia tumida was present in the plankton of Kievka Bay from February through July at a temperature of −1.2 to 14°C with an average population density of 6812 ind/m3 and… (More)

The problem of classification of closed local minimal nets on surfaces of constant negative curvature has been formulated in [3], [4] in the context of the famous Plateau problem in the… (More)

The paper presents descriptions and illustrations for several species of the genera Mesosagitta, Oligoradiata, and Leptosagitta, either new for science or encountered for the first time in the… (More)
