Robust optimization model for uncertain multiobjective linear programs
Journal of Inequalities and Applications, 2018 In this paper, we consider the multiobjective linear programs where coefficients in the objective function belong to uncertainty sets. We introduce the concept of robust efficient solutions to uncertain multiobjective linear programming problems.

Spin-induced scalarization and magnetic fields
Physics Letters B, 2022 In the presence of certain non-minimal couplings between a scalar field and the Gauss-Bonnet curvature invariant, Kerr black holes can scalarize, as long as they are spinning fast enough.

Spontaneous scalarization in generalized scalar-tensor theory [PDF]
Physical Review D, 2019 Spontaneous scalarization is a mechanism that endows relativistic stars and black holes with a nontrivial configuration only when their spacetime curvature exceeds some threshold. The standard way to trigger spontaneous scalarization is via a tachyonic instability at the linear level, which is eventually quenched due to the effect of non-linear terms ...

Applied Sciences, 2018 Using Pareto optimization in Multi-Objective Reinforcement Learning (MORL) leads to better learning results for network defense games. This is particularly useful for network security agents, who must often balance several goals when choosing what action

Scalar-scalar, scalar-tensor, and tensor-tensor correlators from anisotropic inflation [PDF]
Physical Review D, 2010 We compute the phenomenological signatures of a model (Watanabe et al' 09) of anisotropic inflation driven by a scalar and a vector field. The action for the vector is U(1) invariant, and the model is free of ghost instabilities. A suitable coupling of the scalar to the kinetic term of the vector allows for a slow roll evolution of the vector vev, and ...

Viable constraint on scalar field in scalar–tensor theory [PDF]
Classical and Quantum Gravity, 2020 Abstract The scalar–tensor theory can be formulated in both Jordan and Einstein frames, which are conformally related together with a redefinition of the scalar field. As the solution to the equation of the scalar field in the Jordan frame does not have the one-to-one correspondence with that in the Einstein frame,

Spontaneous scalarization of dyonic black hole in Einstein–Maxwell-scalar theory
European Physical Journal C: Particles and Fields, 2023 In this paper, we study the scalarization of the static and spherically symmetric dyonic Reissner–Nordstrom (RN) black holes in the Einstein–Maxwell-scalar theory where the scalar field is coupled to an electromagnetic Chern–Simons term.
