	1. Cappell-Miller analytic torsion on contact manifolds
	SU Guangxiang
	Mathematics 11 December 2013
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Analytic torsion is an important invariant in global analysis. Complex-valued analytic torsion has been studied in recent years. In this paper, we define the Cappell-Miller analytic torsion of the contact complex on contact manifolds. We also get the anomaly formula of the Cappell-Miller analytic torsion in this case.

	2. On some ratios of ergodic sums in continued fractions

	Mathematics 26 February 2013
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:This note is devoted to the multifractal analysis of ratios of ergodic sums for Gauss dynamics T associated to continued fractions.For any irrational number x∈[0,1), let x=[a1(x),a2(x),...] be its continued fraction expansion with an(x)=a1(Tn-1x)being the partial quotients of x. The dimensions of the level sets defined by the ratios of the ergodic sums of a1(x) and a1(Tx)under the system ([0,1], T) and its iteration ([0,1], T2)are obtained.It will be seen that there are some differences between the cases here and the known multifratal analysis.

	3. Strongly Liftable Schemes and the Kawamata-Viehweg Vanishing in Positive Characteristic II
	Xie Qihong
	Mathematics 13 December 2012
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:A smooth scheme X over a field k of positive characteristic is said to be strongly liftable, if X and all prime divisors on X can be lifted simultaneously over W2(k). In this paper, first the author proves that smooth toric varieties are strongly liftable, hence the Kawamata-Viehweg vanishing theorem holds for smooth projective toric varieties. Second, the author proves the Kawamata-Viehweg vanishing theorem for normal projective surfaces which are birational to a strongly liftable smooth projective surface. Finally, the author deduces the cyclic cover trick over W2(k), which can be used to construct a large class ofliftable smooth projective varieties.

	Abstract:A smooth scheme X over a field k of positive characteristic is said to be strongly liftable, if X and all prime divisors on X can be lifted simultaneously over W2(k). Some concrete examples and properties of strongly liftable schemes are given in this paper. As an application, the author proves that theKawamata-Viehweg vanishing theorem in positive characteristic holds on any normal projective surface which is birational to a strongly liftable surface.

	5. Gradient Estimates and Liouville Theorems for Dirac-harmonic maps
	CHEN Qun, Jürgen Jost,SUN Linlin
	Mathematics 07 August 2012
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Dirac-harmonic map is the mathematical version of the super-symmetric nonlinear sigma model in quantum field theory, it includes the two important special cases: harmonic map and harmonic spinor. Many progresses have been made in the existence, regularity, blowup analysis, etc.. Most of the previous results deal with Dirac-harmonic maps from compact manifolds, it is the main aim of the present paper to derive properties of Dirac-harmonic maps from non-compact complete manifolds. Precisely, the authors established gradient estimates for Dirac-harmonic maps from non-compact complete Riemannian spin manifolds into regular balls of the target manifolds, and then apply these estimates to obtain Liouville theorems for Dirac-harmonic maps under certain conditions of the curvatures or energies, especially, they proved Liouville theorems of Dirac-harmonic maps under small energy density conditions.

	8. Deformations of special Legendrian submanifolds with boundary

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this article, for a compact special Legendrian submanifold withboundary of contact Calabi-Yau manifolds we study the deformationof it with boundary confined in an appropriately chosen contactsubmanifold of codimension two which we also call a scafford(Definition 4) by analogy with Butsher[1].Our result shows that it cannot bedeformed under such a boundary confinement. This result may be viewedas supplements of the compact boundless case considered by Tomassini andVezzoni[2].

	9. Variational formulas of higher order mean curvatures

	Mathematics 01 November 2011
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper, we establish the first variational formula and its Euler-Lagrange equation for the total 2p-th mean curvature functional of a n-dimensional submanifold M in a general (n+m)-dimensional Riemannian manifold N. As an example, we prove that closed complex submanifolds in complex projective spaces are critical points of the total 2p-th mean curvature functional, called relatively 2p-minimal submanifolds, for all p. At last, we discuss the relations between relatively 2p-minimal submanifolds and austere submanifolds in real space forms, as well as a special variational problem.

	10. S-λ Bases and S-λ Curves
	Fan Feilong ,Zeng Xiaoming
	Mathematics 23 May 2011
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper the S-λ distributions are presented and the S-λ basis functions are constructed from the S-λ distributions by means of the technique of generating functions and transform factors. These basis functions generate S-λ curves. We show that S-λ curves include Bezier curves, Poisson curves, rational Bezier curves and a lot of other curves. Therefore the researches of this paper provide a unified scheme for dealing with these famous curves. We study the important properties and identities of the S-λ basis functions and S-λ curves. Furthermore, by means of the technique of the generating function, a new convenient and practical method for local changes of S-λ curves is proposed.
