Department of Mathematics

The Department came into existence in 1967 with a major objective to serve as a center of academic excellence in the area of Post Graduate education in Mathematics and to provide research facilities for teaching, training and research in this area. Apart from regular courses like M.A. /M.Sc., Six-Month Pre-Registration Course Work of the  Ph. D./ M. Phil.  Programmes, M. Phil. and Ph. D., presently the department is offering classes/guidance to the students preparing for NET and GATE Examinations also. The Department since its inception has organized various Seminars, Workshops, Refresher Courses and Summer Institutes to train the teachers of the region. In 1992 the department was selected under COSIST by UGC. The Department is receiving NBHM Book Grants since 1992 – 93 till to-day. The Department got financial support from FIST for infrastructure developments. In 2007, the Department was awarded financial assistance under Special Assistance Program (SAP) of UGC for a period of 5 years with Mathematical Modeling as the thrust area. The Department has successfully completed the SAP (DRS-I). The UGC has further approved the department for continuation from DRS(I) to DRS(II) for a period of 5 years (01.04.2013 to 31.03.2018). The Department has completed two minor research projects  under UGC; six major research projects, four of which were funded by UGC and one each funded by DST and DAE. Further one major research project under UGC is presently running in the department. Publications of the Faculty Members during 2015-2016: 41 (International).

Students' Activities

  1. A Summer Camp was organized by the Department of Mathematics, Dibrugarh University during the month of July, 2011 in Dhemaji district and the post graduate students were taking part in the camp as mentors.
  2. A Summer Camp was organised by the Department of Mathematics, Dibrugarh University, Dibrugarh for the High School students of Azad and its peripheral areas in Lakhimpur in collaboration with Lakhimpur Telahi Kamalaboria College, Lakhimpur during 7th July to 13th July, 2014. The students of the department took part in the programme as instructors, where the participants were exposed to various popular aspects of Mathematics in addition to the regular courses.
  3. Two Summer Camps on Mathematics were organized by the Department of Mathematics, Dibrugarh University during the summer vacation. The first camp was held in collaboration with Barekuri Anchalik Yuva Sangha and Jatiya Vidyalay, Barekur from 30th June, 2015 to 7th July, 2015 at Jatiya Vidyalaya, Barekuri, Makum, Tinsukia. Some of the students from the Department of Mathematics, Dibrugarh University were assigned as Mentors in the Camp which was well attended by 60 students of class IX and X from schools of Barekuri and nearby areas.
