The structure of conservative gradient fields
Adrian Lewis, Tonghua Tian
The classical Clarke subdifferential alone is inadequate for understanding automatic differentiation in nonsmooth contexts. Instead, we can sometimes rely on enlarged generalized g…

Ground states and their characterization of spin- Bose-Einstein condensates
Tonghua Tian, Yongyong Cai, Xinming Wu +1
The computation of the ground states of spin- Bose-Einstein condensates (BECs) can be formulated as an energy minimization problem with two quadratic constraints. We discretize…

Partial smoothness and constant rank
Adrian S. Lewis, Jingwei Liang
The idea of partial smoothness in optimization blends certain smooth and nonsmooth properties of feasible regions and objective functions. As a consequence, the standard first-orde…
