	1. Multiple limit cycles for three-dimensional Lotka-Volterra systems
	LUO Yong, LU Gui-Chen, LU Zheng-Yi

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

	Abstract:Multiple limit cycles are shown to appear in three-dimensional Lotka-Volterra systems with various types of interactions formed by mutualism, competition and prey-predator. In this paper, under the density dependance and the nonzero off-diagonal elements of interaction matrix, we classify the three-dimensional Lotka-Volterra systems into ten classes and show that besides the known results for classes 2, 3, 5 and 9, in each class of the remaining six ones, a corresponding system can be constructed to have at least two or three limit cycles based on an algorithmic construction method proposed by Hofbauer and So with a modification of Lu and Luo.

	Abstract:In this paper, the new general extended solitary wave solutions are successfully constructed to a generalized Schr"{o}dinger-Boussinesq equation and a higher-order nonlinear Schr"{o}dinger equation. With the aid of the generally projective Riccati equation method, the corresponding soliton solutions and periodic solutions are given, including ordinary hyperbolic functions, trigonometric functions, rational solutions and these expanding forms.

	3. Blow-up Dynamics of $L^2$ Solutions for theDavey-Stewartson System

	Abstract:In this paper, the blow-up solutions for the Davey-Stewartson system (D-S system, for short)are studied in $L_x^2(mathbb{R}^2)$. First, the nonlinear profile decomposition of solutions for theD-S system is given. Then, the existence of minimal mass blow-up solutions is proved. Finally, by using the characteristic of minimal mass blow-up solutions, the limiting profile and a precisely mass concentration of $L^2$ blow-up solutions for the D-S system are obtained.

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

	Abstract:In this paper, we first give some sufficient conditions for the finite time blow-up result of smooth solutions to the Euler-Poisson magnetohydrodynamic flows. We use the method in cite{JWX} to estimate the total pressure and momentum of inertia, and then deduce the upper and lower bounds of internal energy, finally give the proof of the main result by comparing the bounds.

	Abstract:This paper concerns with the linear and differentiableclassification problems of time-invariant linear control systems(governed by ordinary differential equations) with observation. Asan example, the linear and differentiable classificationresults are expressed explicitly in the two-dimensional case. In some sense, theclassification result obtained partially generalizes P. Brunovsky's one onlinear control systems without observation.

	7. Empirical likelihood method for case-cohort studies
	YU Wen
	Mathematics 22 May 2013
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:The case-cohort design is widely used in large epidemiological studies and prevention trials for cost reduction. In this paper, we propose an empirical likelihood based inferential procedure for the case-cohort design under Cox model. The proposed log-empirical likelihood ratio test statistics for the regression parameters are shown to possess chi-squared limiting distributions. The profile empirical likelihood can be applied to make inferences about linear combinations of the entire parameter vector. The proposed approach which avoids the complex variance estimation is an attractive alternative to the existing Wald-type inferential procedures. Simulation studies are conducted to assess the finite sample performances of the proposed inferential procedures. A real example is also provided for illustration.

	Abstract:The join of two vertex disjoint graphs is obtained from their union by including all edges between the vertices in one graph and the vertices in the other. This paper mainly focused on the calculation formulas of Wiener indices, hyper-Wiener indices and reverse Wiener indices of the join of k graphs based on two definitions.

	9. A Mixed Brownian-Poisson-fractional Model for option pricing
	Liu Qian,Wang Xiaotian
	Mathematics 17 November 2012
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:For option pricing, a mixed model with respect to standard Brownian motion and Poisson fractional process with 'Hurst exponent' being in (1/2,1) is established. We show that although return distributions of stocks are leptokurtic and skewed, have fatter tails than normal distribution and stock return series exhibit long-range dependence, the Black-Scholes formula still holds. We conclude that the skewed and fatter tail distributions as well as long-range dependence in stock return series are not fundamental factors to explain the smile effect of implied volatility in the Black-Scholes formula in some cases.

	10. Liouville type theorem for a parabolic equation involving Pucci operator
	Liu Yong
	Mathematics 10 October 2012
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:The main subject of this paper is the superlinear parabolic equation involving Pucci's operator. Due to the fully nonlinear property of this operator, it is one of the main concerns in the Pde theory. One natural question is whether or not the results for the Laplacian operator has analogies for Pucci's operator. While this is in general the case for elliptic equation, the main purpose of this paper is investigating the similarity between these two operators in the parabolic eqauation catagory. One classicla result for the superlinear parabolic equation involving Laplacian operator is the Liouville type theorem. Due to the importance of these kind of theorems, the Liouville type theorem for parabolic equation involving Pucci's operator is studied in this paper. When the space variable is one dimensional, it is relatively easy to analyze the Pucci operator. The main result of this paper states that in this case, the corresponding equation does not have global positive bounded solution. This result could be used to get certain a priori estimates for a class of fully nonlinear equations.
