Dirac cone, flat band and saddle point in kagome magnet YMn6Sn6. [PDF]
Nat Commun, 2021 Kagome-lattices of 3d-transition metals hosting Weyl/Dirac fermions and topological flat bands exhibit non-trivial topological characters and novel quantum phases, such as the anomalous Hall effect and fractional quantum Hall effect.

Stochastic Saddle Point Problems with Decision-Dependent Distributions [PDF]
SIAM Journal on Optimization, 2022 This paper focuses on stochastic saddle point problems with decision-dependent distributions. These are problems whose objective is the expected value of a stochastic payoff function and whose data distribution drifts in response to decision variables--a

Consensus-Based Optimization for Saddle Point Problems [PDF]
SIAM Journal of Control and Optimization, 2022 In this paper, we propose consensus-based optimization for saddle point problems (CBO-SP), a novel multi-particle metaheuristic derivative-free optimization method capable of provably finding global Nash equilibria.

Kaczmarz method for saddle point systems [PDF]
E3S Web of Conferences, 2021 The Kaczmarz method is presented for solving saddle point systems. The convergence is analyzed. Numerical examples, compared with classical Krylov subspace methods, SOR-like method (2001) and recent modified SOR-like method (2014), show that the Kaczmarz

On Accelerated Methods for Saddle-Point Problems with Composite Structure [PDF]
Computer Research and Modeling, 2021 We consider strongly-convex-strongly-concave saddle-point problems with general non-bilinear objective and different condition numbers with respect to the primal and the dual variables. First, we consider such problems with smooth composite terms, one of

Journal of NeuroEngineering and Rehabilitation, 2021 Introduction After a stroke, a wide range of deficits can occur with varying onset latencies. As a result, assessing impairment and recovery are enormous challenges in neurorehabilitation. Although several clinical scales are generally accepted, they are
