Titles and abstracts. ... Bernard Leclerc; On the dual canonical basis (old and new) . Around 1991, Lusztig, motivated by earlier works of Gelfand and Zelevinsky, introduced a "canonical basis" of the coordinate ring C[N] of the maximal unipotent subgroup N of a simple algebraic group G. This basis was in fact the specialization as q tends to 1 of the dual canonical basis of the quantum enveloping algebra U_q(n) (where n = Lie(N)). ...

... THE SIMPLEST MODEL. ... 13, Moscow 119992, Russia E-mail: san@sai.msu.ru Abstract: The analysis of the simplest model shows that an asteroid ­ rubble pile evolves, depending on the parameter V2d (where V is the average velocity of fragments and d is the average distance between fragments), either as a conglomerate of "independent mutually gravitating clusters" (when V2d < fm, where f is the gravitational constant and m is the average mass of a fragment) or as a "receding cluster" (when V2d > fm). ...

... It is found that the correlation coefficients between these two parameters calculated separately inside and outside the sunspot formation zone ±30 have cyclic variation and occur in anti-phase. This suggests different mechanisms of formation of the corona in the fields of small, medium, and large scales. ... The relationship between the coronal green line brightness (CGLB) and the magnetic field strength (MFS) has been investigated by constructing the corresponding synoptic maps for the 1977-2001. ...
