Spherical twist
WebDec 7, 2024 · Our first result (Theorem 3.5) simplifies an object of a 2-CY triangulated category \mathcal C by applying spherical twists. We show that the positive twist in the lowest HN factor and the negative twist in the highest HN factor decrease the phase spread (see Theorem 3.5 for a precise statement).

Webnothing special about spherical twists in the abstract. However, in practice they remain a useful way of constructing complicated autoequivalences (of D) out of simpler ones (of C). The result also suggests that if we encounter a new kind of autoequivalence then it may be useful to describe it as a spherical twist, particularly if we can nd one Webland) the kernel of this representation is generated by squares of spherical twists. The action of these spherical twists on the Chow ring can be determined explicitly by relating it to the natural subring introduced by Beauville and Voisin. 1.
