Projective Superspace
Ulf Lindström
(Uppsala)
Abstract:
Superfields in Superspace provide very economical means of representing supermultiplets. However, there are limitations on the possible actions one may construct in standard superspace when the number of supersymmetries grow. In projective superspace, superspace is enlarged with one CP(1) at each point. I will explain how this improves the situation and exemplify.

A monotonicity conjecture in holographic RG flows
Flavio Porri
(INFN)
Abstract:
Abstract: Recently the existence of a new quantity which decreases along RG-flows of 4d supersymmetric QFT's with R-symmetry has been conjectured. I will analyze this conjecture from a dual supergravity perspective:
using some general properties of domain-wall solutions dual to R-symmetric RG flows, I will define a function interpolating between the correct values at the UV and IR fixed points. I will finally test its monotonicity properties in a class of examples.
