A bstract We study $$ \mathrm{T}\overline{\mathrm{T}} T ¯ deformations of chiral bosons using the formalism due to Sen. For arbitrary numbers left- and right-chiral bosons, we find that -deformed Lagrangian can be computed in closed form, giving rise a novel non-local...

We study the possibility of making social evaluations of allocations independently of individuals’ preferences over unavailable commodities. This is related to the well-known problem of performing international comparisons of standard of living across countries with different consumption goods. We prove impossibility results which suggest that such evaluations encounter difficulties when the ob...

Perceptual learning (PL) and perceptual expertise (PE) are two fields of visual training studies that investigate how practice improves visual performance. However, previous research suggests that PL can be acquired in a task-irrelevant manner while PE cannot and that PL is highly specific to the training objects and conditions while PE generalizes. These differences are difficult to interpret ...

Abstract We initiate the study of T ¯ -like irrelevant solvable deformations in quantum field theory with boundaries and defects. For this purpose, we employ a general formali...
