We consider the extensions of classical r-matrix for κ-deformed Poincaré algebra which satisfy modified Yang-Baxter equation. Two examples introducing additional deformation parameter (dimension-full 1 κ or dimensionless ξ) are presented. We describe the corresponding quantization (two-parameter κ-Poincaré quantum Hopf algebras) in explicite form as obtained by twisting of standard κ-deformed f...

Abstract This work presents a novel matrix-based method for constructing an approximation Hessian using only function evaluations. The requires less computational power than interpolation-based methods and is easy to implement in programming languages such as MATLAB. As evaluations are required, the suitable use derivative-free algorithms. For reasonably structured sample sets, proven create or...
