Derived brackets in bosonic string sigma-model

Abstract

Nous étudions la théorie des feuilles du monde de la corde bosonique du point de vue du formalisme BV. Nous décrivons explicitement la structure de Poisson dérivée qui se produit lorsque nous développons l'action principale près d'une sous-variété lagrangienne. Les crochets supérieurs de Poisson qui en résultent sont tous dégénérés et essentiellement constants le long de leurs feuilles symplectiques. Les déformations des structures complexes des feuilles du monde définissent une famille de sous-variétés lagrangiennes, paramétrées par le différentiel de Beltrami. L'action de la feuille de mondes dépend non linéairement du différentiel de Beltrami, mais la structure de la non-linéarité est régie par l'équation maîtresse BV. Cela permet de clarifier le mécanisme de factorisation holomorphe des amplitudes des cordes.

Estudiamos la teoría de la hoja del mundo de la cuerda bosónica desde el punto de vista del formalismo BV. Describimos explícitamente la estructura de Poisson derivada que surge cuando expandimos la acción maestra cerca de una subvariedad lagrangiana. Los paréntesis de Poisson superiores resultantes son todos degenerados y esencialmente constantes a lo largo de sus hojas simplécticas. Las deformaciones de las estructuras complejas de la lámina del mundo definen una familia de subvariedades lagrangianas, parametrizadas por el diferencial de Beltrami. La acción de la lámina de mundo depende no linealmente del diferencial de Beltrami, pero la estructura de la no linealidad se rige por la ecuación maestra de BV. Esto ayuda a aclarar el mecanismo de factorización holomórfica de las amplitudes de las cuerdas.

We study the worldsheet theory of bosonic string from the point of view of the BV formalism. We explicitly describe the derived Poisson structure which arises when we expand the Master Action near a Lagrangian submanifold. The resulting higher Poisson brackets are all degenerate and essentially constant along their symplectic leaves. Deformations of the worldsheet complex structures define a family of Lagrangian submanifolds, parametrized by Beltrami differential. The worldsheet action depends nonlinearly on the Beltrami differential, but the structure of nonlinearity is governed by the BV Master Equation. This helps to clarify the mechanism of holomorphic factorization of string amplitudes.

ندرس نظرية ورقة العالم للسلسلة البوزونية من وجهة نظر شكلية BV. نحن نصف صراحة هيكل بواسون المشتق الذي ينشأ عندما نوسع العمل الرئيسي بالقرب من مشعب لاغرانج الفرعي. إن أقواس بواسون الأعلى الناتجة كلها متدهورة وثابتة بشكل أساسي على طول أوراقها الانفعالية. تحدد تشوهات الهياكل المعقدة للورقة العالمية عائلة من المشعبات الفرعية اللاغرانجية، والتي يتم قياسها بواسطة مجموعة بلترامي التفاضلية. يعتمد عمل ورقة العالم بشكل غير خطي على تفاضلية Beltrami، لكن بنية اللاخطية تحكمها المعادلة الرئيسية BV. وهذا يساعد على توضيح آلية التحليل الكلي للارتفاعات الوترية.
