A saddle-point finder and its application to the spin foam model [PDF]
, 2022 We introduce a saddle-point finder that can find the complex saddle points for any analytically continued action. We showcase our saddle-point finder by two examples in the EPRL spin foam model: the single vertex case and the case of triangulation $\Delta_3$.

Distributed saddle point problems: lower bounds, near-optimal and robust algorithms* [PDF]
Optimization Methods and Software, 2020 This paper focuses on the distributed optimization of stochastic saddle point problems. The first part of the paper is devoted to lower bounds for the centralized and decentralized distributed methods for smooth (strongly) convex-(strongly) concave ...

On the Existence of a Saddle Value [PDF]
Journal of Optimization Theory and Applications, 2014 In this work, we achieve a complete characterization of the existence of a saddle value, for bifunctions which are convex, proper, and lower semi continuous in their first argument, by considering new suitably defined notions of special directions of recession. As special cases, we obtain some recent results of Lagrangian duality theory on zero duality

Dirac cone, flat band and saddle point in kagome magnet YMn6Sn6
Nature Communications, 2020 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.

Investigation looking at the repeatability of 20 Society of Master Saddlers (SMS) qualified saddle fitters’ observations during static saddle fit [PDF]
, 2017 Saddle fit is widely considered to be a crucial factor for the health and performance of riding horses; however, there have been no studies looking at the agreement between professionals who fit and assess saddles.

Horse Ammunition. From the History of a Saddle
Вестник Волгоградского государственного университета. Серия 4. История, регионоведение, международные отношения, 2019 Introduction. Horse ammunition was formed historically on a large geographical area. The most important component of it is a saddle. The ancient history of a saddle is not sufficiently investigated.

Saddle pulmonary thromboembolism [PDF]
QJM, 2013 A 27-year-old previously healthy man was presented to the emergency department with acute onset breathlessness since 9 h. He denied a history of fever, cough, chest pain and haemoptysis. There was no history of chest trauma. On examination, he was in respiratory distress with a respiratory rate of 40/min. His oxygen saturation was 85% by pulse oximetry
