In this paper, we use the symbolic computation method to prove the famous Mordell inequality conjecture. By eliminating the constraints using the normalized condition, this problem can be transformed into the non-constraints *** the case of n = 3, we verified that this inequality is correct by cylindrical algebraic decomposition;meanwhile, for the case of n = 4, we verify the inequality is also valid for many cases by using the successive difference substitution method.

The current research on the blockchain includes study on network architecture and the incentive. In this paper, an introduction to the architecture of information technology was given and the goal and research status of the incentive layer of blockchain were illustrated with digital economy development as the backdrop. The existing issuance of token was elaborated from computation, storage and transmission, three core facets of network technology. The development of the token allocation and the path was analyzed to confirm its rationality. It discusses the possible directions and challenges of the future research on blockchain incentive.

我们改进了共偏移距-共反射面(COCRS)法,可用以衰减地滚波,即由于低速、低频/高振幅瑞雷波通常产生的相干噪声。COCRS算子是基于双曲线,因此它可以拟合双曲走时的同相轴,如叠前数据中的反射同相轴。相反,地滚波在共中点(CMP)和共炮点道集中是线性的并可以可以利用COCRS算子鉴别与压制。因此,我们在共偏移距剖面之前共炮道集中搜索反射倾斜和曲率。因为这对反射振幅的危害最小化是最理想的,我们只对在地滚波区多次覆盖的数据进行叠加。在CO剖面前搜索CS道聚集是对常规COCRS叠加的另一个改进。我们使用合成和真实数据集测试了所提出的方法,数据采自伊朗西部地区。我们将本方法压制地滚波的结果与f-k滤波和f-k滤波后常规COCRS叠加压制地滚波的结果进行了比较。结果表明,该方法对真伪滚压制效果优于F-K滤波与传统CRS叠加。然而,计算时间高于其他常规的方法,如f滤波。

This paper deals with the electro-elastic coupling interaction between a piezoelectric screw dislocation which is located inside the elliptical inhomogeneity and an electrically conductive confocal rigid line under remote anti-plane shear stresses and in-plane electrical loads in piezoelectric composite material. The analytical-functions of the complex potentials, stress fields and the image force acting on the piezoelectric screw dislocation are obtained based on the principle of conformal mapping, the method of series expansion, the technical of analytic continuation and the analysis of singularity of complex potentials. The rigid line and the piezoelectric material property combinations upon the image force and the equilibrium position of the dislocation are discussed in detail by the numerical computation.

In this paper, we investigate the Rotating N Loop-Soliton solution of the coupled integrable dispersionless equation (CIDE) that describes a current-fed string within an external magnetic field in 2D-space. Through a set of independent variable transformation, we derive the bilinear form of the CIDE Equation. Based on the Hirota’s method, Perturbation technique and symbolic computation, we present the analytic N-rotating loop soliton solution and proceed to some illustrations by presenting the cases of three- and four-soliton solutions.
