        4月12日下午,应学院邀请,印度Harish-Chandra研究所Chakraborty教授、Hoque博士在我院学术交流厅分别进行了题为“Class numbers of quadratic fields”和“Pell-type equations and class groups of cyclotomic field”的精彩报告,报告由张天平副教授主持。学院青年教师高玉彬、刘杭、王章结,以及相关专业数十名研究生聆听了此次报告。报告还吸引了兄弟院校相关专业的数位教师参与。 
       在报告中,Chakraborty教授讨论了一些二次域的类数。基于与Hoque、Kishi和Pandey共同完成的一些工作,Chakraborty教授从定性和定量两方面分别讨论了实二次域和虚二次域上类数的整除性,并介绍了虚二次域上的3阶理想类群的一些最新进展。

 

        基于与Chakraborty共同完成的一些工作,Hoque博士讨论了一些Pell类型方程的可解性。然后,应用已知的结果来寻找具有非平凡类群的分圆域的集合。最后,构造了一类具有三阶元素的类群的分圆域的集合。 

 

        报告结束后,Chakraborty教授与Hoque教授还同与会师生进行了深入的互动交流。

        Chakraborty教授简介:
