Revisiting the conformally soft sector with celestial diamonds

چکیده

Celestial diamonds encode the structure of global conformal multiplets in 2D celestial CFT and offer a natural language for describing conformally soft sector. The operators appearing at their left right corners give rise to factorization theorems, bottom correspond conserved charges, top dressings. We show that charges can be expressed terms light ray integrals select modes appropriate weights. They reside memory diamonds, ascend generalized currents. then identify associated Goldstone with Faddeev-Kulish dressings compute sub-leading gauge theory gravity which are important finding nontrivial central extensions. Finally, we combine these ingredients speculate on effective descriptions sector CFT.

Testing of Soft Regolith Dynamic Anchors for Celestial Exploration

Recent exploration missions to celestial bodies have shown an increasing demand for surface based landers and rovers designed to perform experiments on the ground, rather than relying purely on traditional orbiting observatories. Many of the scientifically interesting locations have proven hazardous and difficult to reach and traverse, driving the need for different methods of locomotion. Some ...

Revisiting the Soft Global Cardinality Constraint

Pierre Schaus, Pascal Van Hentenryck, Alessandro Zanarini Dynadec, Brown University {pschaus,pvh,alessandro.zanarini}@dynadec.com Abstract. The Soft Global Cardinality Constraint (softggc) relaxes the Global Cardinality Constraint (gcc) by introducing a violation variable representing unmet requirements on the number of value occurrences. A first domain consistent filtering algorithm was introd...
