Shape Optimization for the Principal Eigenvalue of the Pucci Operator in Three Dimensions
Mohan Mallick, Ram Baran Verma
The paper studies how the shape of a three‑dimensional domain affects the principal eigenvalue of the fully nonlinear Pucci extremal operator, showing that a symmetric, unsheared d…

Existence and Multiplicity results for Weakly coupled system of Pucci's extremal operator
Karan Rathore, Mohan Mallick
In this work, we investigate the existence of multiple positive solutions for a weakly coupled system of nonlinear elliptic equations governed by Pucci extremal operators. Specific…
