چکیده
QFTs with local topological operators feature unusual sectors called ``universes,'' which are separated by infinite-tension domain walls. We show that such systems have relevant deformations exactly-calculable effects. These allow one to dial the vacuum energy densities of universes. describe applications these confinement in 2d gauge theories, as well a curious violation effective field theory naturalness principle.

Bialgebra deformations of certain universal enveloping algebras
Let A denote a bialgebra over a field k and let At = A[[t]] denote the ring of formal power series with coefficients in A. Assume that A is a free algebra over k with a basis of primitives. We give a simple construction which makes At a bialgebra deformation of A. Usually At is neither commutative nor cocommutative. This construction yields deformations of bialgebras associated with families of...
متن کاملUniversal deformations, rigidity, and Ihara’s cocycle
In [Iha86b], Ihara constructs a universal cocycle Gal ( Q/Q ) −→ Zp[[t0, t1, t∞]]/ ((t0 + 1)(t1 + 1)(t∞ + 1)− 1) arising from the action of Gal ( Q/Q ) on certain quotients of the Jacobians of the Fermat curves
متن کاملSlodowy Slices and Universal Poisson Deformations
We classify the nilpotent orbits in a simple Lie algebra for which the restriction of the adjoint quotient map to a Slodowy slice is the universal Poisson deformation of its central fibre. This generalises work of Brieskorn and Slodowy on subregular orbits. In particular, we find in this way new singular symplectic hypersurfaces of dimension 4 and 6.

متن کاملUniversal isomonodromic deformations of meromorphic rank 2 connections on curves
We consider tracefree meromorphic rank 2 connections over compact Riemann surfaces of arbitrary genus. By deforming the curve, the position of the poles and the connection, we construct the global universal isomonodromic deformation of such a connection. Our construction, which is specific to the tracefree rank 2 case, does not need any Stokes analysis for irregular singularities. It is thereby...
متن کاملProcrustean statistical inference of deformations
A two step method has been devised for the statistical inference of deformation changes. In the first step of this method and based on Procrustes analysis of deformation tensors, the significance of the change in a time or space series of deformation tensors is statistically analyzed. In the second step significant change(s) in deformations are localized. In other words, they are assigned to ce...
