  • Supercongruences:  The numbers which occur in Ap\'{e}ry's  proof of the irrationality of  zeta(2) and zeta(3)  have many interesting congruence properties.Work started with F. Beukers and D. Zagier,  then extended by G. Almkvist, W. Zudilin and S. Cooper recently has complemented the Ap\'{e}ry numbers with set of sequences know as Ap\'{e}ry-like numbers which share many of the remarkable properties of the Ap\'{e}ry numbers. We study supercongruences properties  of Ap\'{e}ry-like numbers. 
  • Differential Operators: There are many interesting connections between differential operates and modular forms. Using Rankin-Cohen type differential operators on Jacobi forms/ Siegel modular forms we study certain arithmetic of Fourier coefficients. 
  • Convolution sums and applications: We compute convolution sums of divisor function using the theory of modular forms and quasi modular forms and apply those to find number of representations of an integer by certain quadratic forms. 
  • Representations of numbers by quadartic forms:  We find number of representations of an integer by certain quadratic forms by computing modular forms/ theta series.

Partial Differential Equations

Mithun Kumar Das
Nabin Kumar Jana

Disordered systems pops up quite often in physics (spin glass), biology (artificial neural network), social sciences (matching) and many other places. To analyze, usually these systems are identified with the stochastic models. My main research interest is on the application of probabilistic tools to analyze these stochastic models.

Panchugopal Bikram

My Primary research areas are functional analysis and Ergodic Theory. My  central  research area is operator algebra and it evolves  around operator algebra. I study one parameter family of endomorphisms on von Neumann algebras. 

I also  study structure theory  of von Neumann algebras, Connes's classifications theory of type III factors and various others property of  type III factors and  verious dynamical system on von Neumann algebras.
