چکیده

Working in a superspace, we compute the Lie-point symmetries for the supersymmetric two bosons equations. Computer algebra has helped us to skip the tedious calculations. Translational symmetry supergroups are used to reduce the supersymmetric two bosons equations to an ordinary differential supersystem which involves two even and two odd dependent variables. Some explicit solutions are presented. PACS numbers: 02.20.Sv, 02.30.Jr, 11.30.Pb. Résumé Dans le superespace, nous calculons le groupe de Lie des symétries pour les équations à deux bosons supersymétriques. Le programme GLie écrit dans le langage MAPLE nous permet d’écrire facilement les superéquations déterminantes qui conduisent aux générateurs de la superalgèbre correspondante. On impose l’invariance par translations des solutions pour réduire le supersytéme à un supersystème contenant une seule variable indépendante. Ce dernier se décompose en quatre équations contenant deux variables dépendantes paires et deux impaires. Finalement, on présente quelques solutions explicites.

Supersymmetries in Calabi - Yau Geometry

We consider a class of Lie superalgebra, called spinc supersym-metry algebras, constructed from spinor representation. They are motivated by supersymmetry algebras used by physicists. On a Riemannian manifold, a KK ahler manifold, and a hyperkk ahler manifold respectively, it is known that some natural operators on the space of diierential forms span spinc (2), spinc(3) and spinc (5) supersymme...

Deconstructing Supersymmetry

Two supersymmetric classical mechanical systems are discussed. Concrete realizations are obtained by supposing that the dynamical variables take values in a Grassmann algebra with two generators. The equations of motion are explicitly solved. A genuine Lie group, the supergroup, generated by supersymmetries and time translations, is found to act on the space of solutions. For each system, the s...

Non-Abelian vacua in D=5, N=4 gauged supergravity

We study essentially non-Abelian backgrounds in the five dimensional N=4 gauged SU(2)×U(1) supergravity. Static configurations that are invariant under either the SO(4) spatial rotations or with respect to the SO(3) rotations and translations along the fourth spatial coordinate are considered. By analyzing consistency conditions for the equations for supersymmetric Killing spinors we derive the...

Multi-black holes from nilpotent Lie algebra orbits

For N ≥ 2 supergravities, BPS black hole solutions preserving four supersymmetries can be superposed linearly, leading to well defined solutions containing an arbitrary number of such BPS black holes at arbitrary positions. Being stationary, these solutions can be understood via associated non-linear sigma models over pseudo-Riemaniann spaces coupled to Euclidean gravity in three spatial dimens...
