Extending Lagrangian transformations to nonconvex scalar conservation laws
Prerona Dutta
The present paper studies a method of finding Lagrangian transformations, in the form of particle paths, for all scalar conservation laws having a smooth flux. These are found usin…

Metric entropy for functions of bounded total generalized variation
Rossana Capuani, Prerona Dutta, Khai T. Nguyen
We establish a sharp estimate for a minimal number of binary digits (bits) needed to represent all bounded total generalized variation functions taking values in a general totally…

Covering numbers for bounded variation functions
Prerona Dutta, Khai T. Nguyen
In this paper, we provide upper and lower estimates for the minimal number of functions needed to represent a bounded variation function with an accuracy of epsilon with respect to…
