Wall-Crossing from Supersymmetric Galaxies
We give an elementary physical derivation of the Kontsevich-Soibelman wall crossing formula, valid for any theory with a 4d N = 2 supergravity description. Our argument leads to a slight generalization of the formula, which relates monodromy to the BPS spectrum.
متن کاملWall-crossing made smooth
In D = 4,N = 2 theories on R, the index receives contributions not only from single-particle BPS states, counted by the BPS indices, but also from multi-particle states made of BPS constituents. In a recent work [1], a general formula expressing the index in terms of the BPS indices was proposed, which is smooth across walls of marginal stability and reproduces the expected single-particle cont...
متن کاملWall-crossing Functors
Db(Coh(Aθ λ )) ∼ −→ D(Coh(Aλ)) for two different generic θ, θ′. These derived equivalences will play a crucial role in proving that ImCCv ⊂ Lω[ν]. They were introduced in [BPW, Section 6] under the name of twisting functors. Let us recall from Lecture 3 that abelian localization holds for (λ + nθ, θ) for all n sufficiently large, see Proposition 2.2 there. Also recall that Coh(Aλ) ∼ −→ Coh(Aλ+n...
متن کاملWall Crossing and M-Theory
We study BPS bound states of D0 and D2 branes on a single D6 brane wrapping a CalabiYau 3-fold X. When X has no compact 4-cyles, the BPS bound states are organized into a free field Fock space, whose generators correspond to BPS states of spinning M2 branes in Mtheory compactified down to 5 dimensions by a Calabi-Yau 3-fold X. The generating function of the D-brane bound states is expressed as ...
متن کاملSupersymmetric Domain Wall World from D=5 Simple Gauged Supergravity
We provide explicit examples of supersymmetric domain walls of a fivedimensional simple, N=2 U(1) gauged supergravity theory constructed by Gunaydin, Townsend and Sierra. These conformally flat solutions interpolate between supersymmetric isolated anti-deSitter vacua, satisfy the Killing spinor (first order) differential equations, have the energy density related to the cosmological constants o...
