Gopakumar–Vafa invariants and wall-crossing

چکیده
In this paper, we give a generalization of mathematical definition Gopakumar–Vafa (GV) invariants on Calabi–Yau 3-folds introduced by Maulik and the author, using an analogue BPS sheaves Davison–Meinhardt coarse moduli spaces one dimensional twisted semistable with arbitrary holomorphic Euler characteristics. We show that our generalized GV are independent stability conditions, conjecture they also characteristics, so define same invariants. As application, will flop transformation formula

Wall 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 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 کاملA Wall-crossing Formula for Gromov-witten Invariants under Variation of Git Quotient
We prove a quantum version of Kalkman’s wall-crossing formula [37], [44] comparing intersection pairings on geometric invariant theory (git) quotients related by a change in polarization. Each expression in the classical formula is quantized in the sense that it is replaced by an integral over moduli spaces of certain stable maps; in particular, the wall-crossing terms are gauged Gromov-Witten ...
متن کاملWall-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.
