 Moduli spaces of (semi)stable vector bundles on tree-like curves The automorphism group of the moduli space of semi stable vector bundles Relation with bivariate semi stable distribution is established. The reaming orbital configurations were semi stable over the time scale investigated. semi-stability
 We study the characterization of noncommutative semi-stability through free cumulant transform and develop the free semi-stability and domain of semi-stable attraction in free probability theory. Semi-stability of reductive group schemes over curves We also show that a major open problem in approximation theory may be formulated in terms of a cohomology vanishing on P2 and we discuss a possible connection between semi-stability and the conjectured answer to this open problem. The purpose of this paper is to introduce and study the concepts of discrete semi-stability and geometric semi-stability for distributions with support inZ+. Properties of discrete geometric semi-stable distributions are deduced from the results obtained for discrete semi-stability. 更多 semi-stable
 The EPR spectrum of the semi-stable free radicals TEMPOL, ABTS?+ or DPPH is gradually eliminated during irradiation, and this system represents a simple technique for the evaluation of TiO2 activity. The existence of semi-stable periodic orbits is proved. Generalized Chow Forms and Reduction of Semi-Stable Varieties Log Structures on Generalized Semi-Stable Varieties We construct the obstruction such that the so-called semi-stable log structures exists if and only if the obstruction vanishes. 更多 semistable
 We consider actions of compact real Lie GroupsK on complex spacesX such that the associated reducedK-space admits a semistable quotient, e.g.X is a Stein space. Semistable principal bundles-II (positive characteristics) In this paper, we will formulate a general (parameter dependent) semistability concept for such triples, which generalizes the classical Hilbert--Mumford criterion, and we establish the existence of moduli spaces for the semistable objects. On the structure of rigid semistable sheaves on algebraic surfaces We prove that for any rigid sheafF (Ext1 (F, F) = 0) that is Mumford-Takemoto semistable with respect toH there exists an exceptional set (E1,..., En) of sheaves onS such thatF can be constructed from {Ei} by means of a finite sequence of extensions. 更多 In this paper we invesigate the relative position of limit cycles of the system dx/dt=-y-y~2+mxy+dx,dy/dt=x(1+ax)(1)where α<0 and dm≠0. It is already known, that(1) can have limit cycles only when dm>0 and|d|<|m|. System (1)has four elementary critical points: O(0,0), M(0,-1), N'(-1/a,y_1'), R'(-a,y_2'), (y_1'>y_2'), where O and R' have index +1, M and N' have index -1.

The main result in § 1 is the following: Theorem: (ⅰ)In case m>-a>0 and d>0 sufficiently small system, (1) has just two limit cycles, appearing separately in the neigh bourhood of 0 and R'. (ⅱ) In case-a>m>0, when d increases from zero, limit cycles appear first in the neighbourhood of O, and later also in the neighbourhood of R', they may exist at the same time.
