Mathematics Programmes

SPS offers two programmes in Mathematics, namely, M.Sc. and Ph.D.

M.Sc. in Mathematics:


  • 12 Core courses + 1 Project + 3 Electives for a total of 16 courses.
  • A project is a compulsory course.
  • Each course carries 4 credits for a total of 64 credits.

Ph.D. in Mathematics:

After clearing the entrance examination and interview, a student with an M.Phil degree in Mathematics or with an M.A./M.Sc. degree in Mathematics and a valid UGC-CSIR/NBHM JRF can enrol for a Ph.D. programme in Mathematics at SPS, JNU. For details regarding eligibility requirements and dates of examination and interview, please visit JNU's Admissions page.

Selected students  have to do a course work during the first year. An advisor will be assigned only if the student finishes the course work with suitable grades.

Course work in Mathematics (2 semesters)

Students are required to obtain at least 14 credits during the two semesters of course work.

  • The core courses PS 641M, PS 642M and PS 643M of 3 credits each are essential for students to expand their knowledge of basic Mathematics for doing research. Typically these are covered in the 1st semester.
  • Apart from the three core courses totalling 9 credits, depending upon the courses being offered and the availability of faculty, students may opt for one of the following combinations for the remaining 5 credits in their 2nd semester:
    1. One research course and one of the three optional courses PS 644M, PS 645M or PS 712M.
    2. Two research courses (3 credits each).

Core Courses:

PS 641M     Algebra (3 credits)
PS 642M     Analysis (3 credits)
PS 643M     Topology (3 credits)

Optional Courses:

PS 644M     Topological Groups (2 credits)
PS 645M     Functional Analysis and Operator Theory (2 credits)
PS 712M     Algebraic Number Theory (3 credits)
PS 646M     Research Course I (3 credits)
PS 647M     Research Course II (3 credits)
