Dual Anti-de Sitter Superalgebras from Partial Supersymmetry Breaking
The partial breaking of supersymmetry in anti\char21{}de Sitter space can be accomplished using two of four dual representations for the massive $\mathrm{OSp}(1,4)$ spin-3/2 multiplet. The procedure gives rise to a set of dual $N=2$ supergravities and supersymmetry algebras.
Nonlinear realization of partially broken N=2 AdS supersymmetry in two and three dimensions
Abstract We investigate the nonlinear realization of partially broken N =2 global supersymmetry in the D =2 and 3 anti-de-Sitter (AdS) space. We particularly study Nambu–Goldstone degrees of freedom for the N =2 AdS supersymmetry partially broken down to N =1 AdS supersymmetry, where we observe a NG fermion of the broken supersymmetry and a NG boson of the internal symmetry which form a NG multiplet. Based on the nonlinear realization method, we construct a superspace formalism for 2- and 3-dimensional AdS space and evaluate the covariant derivatives and supervielbeins for the AdS superspace. Finally, we obtain the nonlinear transformation laws and the lowest order of effective Lagrangians.
Do Potential People Have Moral Rights?
By a potential person I shall mean an entity which is not now a person but which is capable of developing into a person, given certain biologically and/or technologically possible conditions. This is admittedly a narrower sense than some would attach to the term ‘potential'. After all, people of the twenty-fifth century, if such there will be, are in some sense potential people now, even though the specific biological entities from which they will develop, i.e. the particular gametes or concepti, do not yet exist. For there do exist, in the reproductive capacities of people now living and in the earth's resources, conditions adequate to produce these future people eventually, provided of course that various possible catastrophes are avoided. Indeed, in some sense of ‘potential’ there have been countless billions of potential people from the beginning of time. But I am concerned not with such remote potentialities but with currently existing entities that are capable of developing into people.
