We study a class of rational hyperelliptic fibrations that can serve as a natural higher-genus analogue of rational elliptic
fibrations from the standpoint of Mordell-Weil lattices. As a corollary, we obtain certain generalizations of the root lattices.
We also describe the torsion part.

The main result is a boundedness theorem forn-complements on algebraic surfaces. In addition, this theorem is used in a classification of log Del Pezzo surfaces and birational
contractions for threefolds.

For a nonnegative strictly stationary random sequence satisfying the “minimal” dependence condition necessary and sufficient conditions for the relative stability are found. As an application the well-known Khinchine stability result for i.i.d. random variables is proved for uniformly strong mixing sequences. 相似文献

Motivated by applications in manufacturing systems and computer networks, in this paper, we consider a tandem queue with feedback.
In this model, the i.i.d. interarrival times and the i.i.d. service times are both exponential and independent. Upon completion
of a service at the second station, the customer either leaves the system with probability p or goes back, together with all customers currently waiting in the second queue, to the first queue with probability 1−p. For any fixed number of customers in one queue (either queue 1 or queue 2), using newly developed methods we study properties
of the exactly geometric tail asymptotics as the number of customers in the other queue increases to infinity. We hope that
this work can serve as a demonstration of how to deal with a block generating function of GI/M/1 type, and an illustration
of how the boundary behaviour can affect the tail decay rate. 相似文献

We study the class of r.i. spaces in which Cesaro means of any weakly null martingale difference sequence is strongly null.
This property is related to the Banach-Saks property. We show that in classical (separable) r.i. spaces (such as Orlicz, Lorentz
and Marcinkiewicz spaces) these properties coincide but this is no longer true for general r.i. spaces. We locate also a class
of r.i. spaces having this property where an analogue of the classical Dunford-Pettis characterization of relatively weakly
compact subsets in L
1 holds.

The Index theorem for holomorphic line bundles on complex tori asserts that some cohomology groups of a line bundle vanish according to the signature of the associated hermitian form. In this article, this theorem is generalized to quasi-tori, i.e. connected complex abelian Lie groups which are not necessarily compact. In view of the Remmert–Morimoto decomposition of quasi-tori as well as the Künneth formula, it suffices to consider only Cousin-quasi-tori, i.e. quasi-tori which have no non-constant holomorphic functions. The Index theorem is generalized to holomorphic line bundles, both linearizable and non-linearizable, on Cousin-quasi-tori using L2-methods coupled with the Kazama–Dolbeault isomorphism and Bochner–Kodaira formulas. 相似文献
