Frob enius endomorphisms of linear spaces Alexander E. Guterman My research interests are in ring theory, linear algebra and combinatorics. In particular, I investigate transformations on matrices over different algebraic structures, preserving some matrix properties, sets or invariants. ... I was investigating monotone matrix transformations and developed method of matrix deformations and chain method in order to classify monotone linear and additive transformations on matrices. ...

... Parameters of the Moon-perturbed orbit . ... From orbits consistent with this limitation and with the date of the launch October 1, 2000 as an example, an orbit was selected with apogee directed to the North Galactic pole at the begining and rotation of orbit plane was maximized. The initial state vector is given in the inertial coordinate system in epoch J2000.0. ... The orbit has initial perigee radius Rp=7000.0 km, initial apogee radius Ra=343000.0 km and initial period T=8.453 days. ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...
