शासकीय नागार्जुन स्नातकोत्तर विज्ञान महाविद्यालय ,रायपुर

Government Nagarjuna Post Graduate College of Science, Raipur

Established 1948

Affiliated to Pt. Ravishankar Shukla University Raipur

1.     BRIEF HISTORY OF THE DEPARTMENT

The department of Mathematics was established in the year 1948 with under-graduate classes headed by Prof. R. S. Iyyar. After some years, in 1956 post- graduate classes were introduced. Keeping in mind to generate resources for income, the department introduced Information Technology subject in under-graduate classes in the year 2000 with combination of Maths, Physics & IT. At present the IT department operates independently. Major thrust areas of research activities are being carried out on Fixed point theory, Fourier Analysis & Wavlets, cryptography.
