Research summary

Vijay Gupta works in approximation theory, a branch of mathematics that studies how complicated functions can be estimated or reconstructed using simpler building blocks called operators, often built from special polynomials (like Laguerre, Touchard, Bernoulli, or Charlier polynomials). Much of the work focuses on defining new mathematical operators, analyzing how quickly they converge to the functions they approximate, and combining or composing different operator types to improve or generalize existing approximation methods.
