“…Thus the "almost singular" manifolds close to a topological phase transition are dynamically preferred. 38 This is somewhat surprising, because the potential has still many unlifted flat 37 In the related case of SU(2) enhancement it was proven in [26] that the Out-picture LEEA cannot be extended to an SU (2) invariant action without taking into account the threshold corrections. 38 For a quantitative analysis of this effect for hyperbolic potentials see [87].…”

“…In particular, only very limited results exist on how to explicitly compute the hypermultiplet metric in string or M-theory. The best studied subsector is the universal hypermultiplet, which at tree level is described by the coset U (1,2) U (1)×U (2) , but receives non-trivial quantum corrections [36][37][38]. The tree level result for the neutral hypermultiplets can be obtained through the c-map [39,40], but only little is known about quantum corrections (see [41] for a review).…”

In this thesis we construct five‐dimensional gauged supergravity actions which describe flop and conifold transitions in M‐theory compactified on Calabi‐Yau threefolds. While the vector multiplet sector is determined exactly, we use the Wolf spaces $X(1+N) = {{U(1+N,2)}\over{U(1+N) \times U(2)}}$ to model the universal hypermultiplet together with N charged hypermultiplets corresponding to winding states of M2‐branes. After specifying the hypermultiplet sector the actions are uniquely determined by M‐theory. As an application we consider five‐dimensional Kasner cosmologies. Including the dynamics of the winding modes, we find smooth cosmological solutions which undergo flop and conifold transitions. Instead of the usual runaway behavior the scalar fields of these solutions generically stabilize in the transition region where they oscillate around the transition locus. The scalar potential thereby induces short episodes of accelerated expansion in the space‐time.

We construct gauged supergravity actions which describe the dynamics of M-theory on a Calabi-Yau threefold in the vicinity of a conifold transition. The actions explicitly include N charged hypermultiplets descending from wrapped M2-branes which become massless at the conifold point. While the vector multiplet sector can be treated exactly, we approximate the hypermultiplet sector by the non-compact Wolf spaces X(1 + N ). The effective action is then uniquely determined by the charges of the wrapped M2-branes.

Instantons and wormholes for the universal hypermultiplet

In this paper we present supersymmetric instanton and non-supersymmetric wormhole solutions for the universal hypermultiplet sector of d = 4 N = 2 supergravity theories. Instantons and wormholes are constructed as saddle points dominating transition amplitudes between states of definite axionic shift charge, using an approach due to Coleman and Lee. Our solutions are constructed in terms of the conserved Noether charges associated with the global SU (2, 1) symmetry of the universal hypermultiplet action. The conditions imposed by regularity on the charges are discussed.
