摘要:
In this paper, we study the oscillatory behavior of solutions of a class of damped fractional partial differential equations subject to Robin and Dirichlet boundary value conditions. By using integral averaging technique and Riccati type transformations, we obtain some new sufficient conditions for oscillation of all solutions of this kind of fractional differential equations with damping term. Our results essentially enrich the ones in the existing literature. Finally, we also give two specific examples to illustrate our main results.

Abstract: Tax is the main form of revenue in our country, affecting the economic development of China. We build multivariate linear regression equation and carry on stepwise regression by analyzing the main factor affecting the tax revenue growth. At last, we obtain the main factor affecting the tax revenue of Hunan province, and explore the effects of tax on the financial income and economic development.#@#@#摘要: 税收是我国财政收入的主要形式,影响着我国经济的发展。本文通过对影响税收收入增长的主要因素进行分析,构建多元线性回归方程,并进行逐步回归,从而得出影响湖南省税收收入的主要因素,了解税收对于财政收入和经济发展的作用。

摘要:
By employing continuation theorem of the coincidence degree, and inequality technique, some sufficient conditions are established for the existence of periodic solution and global exponential stability of fuzzy cellular neural networks with time-varying delays. These results have important leading significance in the design and applications of globally stable neural networks. Moreover an example is given to illustrate the effectiveness and feasible of results obtained.
