Duality and a Riemann metrics in theory of a second order ODE’s
, 2017 A properties of integral curves of ODE’s of the second order d2 dx2 yx = Qx, y, y′ and of the first order d dxyx = Qnx,y Pnx,y with a help of conformal 4D- Riemann metrics of Fefferman and Walker types are investigated.

SciPost Physics, 2023 We propose bi-critical and tri-critical theories between chiral spin liquid (CSL), topological superconductor (SC) and charge density wave (CDW) ordered Chern insulator with Chern number $C=2$ on square, triangular and Kagome lattices.

Duality for unbounded order convergence and applications [PDF]
, 2017 Unbounded order convergence has lately been systematically studied as a generalization of almost everywhere convergence to the abstract setting of vector and Banach lattices. This paper presents a duality theory for unbounded order convergence. We define

A scaling theory for the long-range to short-range crossover and an infrared duality [PDF]
, 2017 We study the second-order phase transition in the d-dimensional Ising model with long-range interactions decreasing as a power of the distance 1/rd+s.

The data on the boundary at order $$\alpha '$$ α ′
European Physical Journal C: Particles and Fields, 2023 The least action principle indicates that for the open spacetime manifolds, there are data on the boundary. Recently, it has been proposed that the data for the effective actions at order $$\alpha '$$ α ′ are the values of the massless fields and their ...

On Lagrange duality theory for dynamics vaccination games [PDF]
Ricerche di Matematica, 2018 The authors study an infinite dimensional duality theory finalized to obtain the existence of a strong duality between a convex optimization problem connected with the management of vaccinations and its Lagrange dual.

α′ ‐Corrected Poisson‐Lie T‐Duality [PDF]
Fortschritte der Physik, 2020 We propose leading order α′ ‐corrections to the Poisson‐Lie T‐duality transformation rules of the metric, B‐field, and dilaton. Based on Double Field Theory, whose corrections to this order are known, we argue that they map conformal field theories to ...

Background Independence and Duality Invariance in String Theory. [PDF]
Physical Review Letters, 2016 Closed string theory exhibits an O(D,D) duality symmetry on tori, which in double field theory is manifest before compactification. I prove that to first order in α^{'} there is no manifestly background independent and duality invariant formulation of ...

Conic Duality for Multi-Objective Robust Optimization Problem
Mathematics, 2022 Duality theory is important in finding solutions to optimization problems. For example, in linear programming problems, the primal and dual problem pairs are closely related, i.e., if the optimal solution of one problem is known, then the optimal ...

Duality invariant cosmology to all orders in α′ [PDF]
Physical Review D, 2019 While the classification of $\alpha'$ corrections of string inspired effective theories remains an unsolved problem, we show how to classify duality invariant $\alpha'$ corrections for purely time-dependent (cosmological) backgrounds.
