Talk in Inaugural Session of NCETMMS-2015 by Linfan MAO

Ladies and Gentlemen, Good Morning

It is my pleasant duty to extend my sincere thank to the organizer — Calcutta Mathematical Society on behalf of a Chief Guest, thanks also go to all attendants to be here for a common interest: mathematics or mathematical sciences.

 As we known, the function of science is realizing the natural world and developing our society in coordination with natural laws, and the function of mathematics is provide quantitative analysis tools or ways for holding on the reality of things by observation. Thus, sciences should be served to the social practice of human beings.

 The practice can not do well without theory, and also, the theory can not develop without practice test. Today, a main character for developing of science is its cross promotion and common development on different branches of science, also called, interdisciplinary, which results in many new developing trends in mathematics and other sciences, for examples, the applications of interaction systems to economy or ecology, and combinatorics to classical mathematics and mathematical sciences.

 I wish each attendant will use this opportunity to fully exchange well, display your results and learn more from others. I believe you will not come in vain on this conference.

 Finally, I wish the conference a complete success! Thanks to everyone!

毛林繁在印度“全国数学及数学科学发展趋势学术交流大会”开幕式的讲话

女士们、先生们，大家早上好！

作为主宾，请允许我向会议组织者，加尔各答数学会表示感谢！同时，对各位代表因对数学或数学科学的共同兴趣而出席本次会议表示感谢！

我们知道，科学的功用在于认识自然，进而使人类社会的发展符合自然规律，对应的，数学的作用在于为掌握自然真实提供定量分析的工具或解决方法，故此，科学应当服务于人类的社会实践。

实践发展离不开理论指导，同样，理论的推进也离不开实践检验。二十一世纪科学发展的一个显著特征是不同学科间交叉发展、共同进步，进而导致数学及其他科学发展的一些新趋势和动向，例如，粒子物理在的相互作用系统在经济学和生态学中的应用，以及组合学在经典数及数学科学发展中的应用等。

我希望每一位与会者应用这次机会充分交流，展示成果，同时向其他与会者学习知识与方法。我相信每一位与会者不会因此而是徒劳的。

最后，预祝本次会议圆满成功。谢谢大家！

[编者注释]印度加尔各答数学会(Calcutta Mathematical Society)成立于1908年，是有着百年老店声誉的学会，也正因为此，它成了代表印度整个数学界的数学会（印度全国及各帮后来均没有再成立数学会），这也是为什么它每年举办的数学会议都冠以“全国”二字的缘由。
