Preserving Contexts for Soft Conformance Relation [chapter]

David de Frutos Escrig, Carlos Gregorio Rodróguez
2005 Lecture Notes in Computer Science  
A new definition, that we called soft conformance, is given. Then, we concentrate on the study of the conditions under which a context preserves the soft conformance relation of two agents.  ...  Since the addition of extraneous actions to the implementation allows to define malicious contexts that would not preserve the conformance relation, such a characterisation of the family of contexts preserving  ...  In fact, these contexts would be different for each pair in the relation, and therefore, out of some trivial cases, we cannot look for a family of contexts totally preserving the conformance relation.  ...

Mapping SYK to the Sky [article]

Sabrina Pasterski, Herman Verlinde
2022 arXiv   pre-print
Here we propose that a 2D generalization of SYK provides an instructive toy model for the soft limit of the gravitational sector in 4D asymptotically flat spacetime.  ...  We find that the symmetries and soft dynamics of the 2D SYK model capture the salient features of the celestial theory: exhibiting chaotic dynamics, conformal invariance, and a w_1+∞ symmetry.  ...  Treiman Fellowship at the Princeton Center for Theoretical Science.

A Comment on the holographic renormalization group and the soft dilaton theorem

Enrique Álvarez, César Gómez
2000 Physics Letters B  
The equivalence between the holographic renormalization group and the soft dilaton theorem is shown for a class of wrapped metrics solutions of the string beta function equations for the bosonic string  ...  From the Hamilton-Jacobi point of view [8] this sign could be related with the wrong sign of the conformal factor in Einstein action while in the context of the soft dilaton theorem the sign is related  ...  Let us evaluate it for a conformally invariant string background, i.e., to lowest order in α , a solution of the equations: R µν − ∇ µ ∇ n Φ = 0 ∇ 2 Φ + (∇Φ) 2 = 0 (9) Based on the soft dilaton theorem  ...

Hidden conformal symmetry in tree-level graviton scattering

Florian Loebbert, Matin Mojaza, Jan Plefka
2018 Journal of High Energy Physics  
The presence of this conformal symmetry is indicated by the dilaton soft theorem in string theory, and it is reminiscent of the conformal invariance of gluon tree-level amplitudes in four dimensions.  ...  We argue that the scattering of gravitons in ordinary Einstein gravity possesses a hidden conformal symmetry at tree level in any number of dimensions.  ...  See Footnote 8 in this context.  ...
