The Role of Pre-Commitments and Engle Curves in Thailand’s Aggregate Energy Demand System
Energies, 2022 In the present paper, an investigation into Thailand’s energy demand is performed to determine if: (1) a linear or nonlinear Engel curve better explains the relationship between income and energy consumption, and (2) systems with pre-commitments better ...

Maximizing products of linear forms, and the permanent of positive semidefinite matrices [PDF]
, 2022 We study the convex relaxation of a polynomial optimization problem, maximizing a product of linear forms over the complex sphere. We show that this convex program is also a relaxation of the permanent of Hermitian positive semidefinite (HPSD) matrices ...
