高规范理论的代数表述

Algebraic formulation of higher gauge theory

Roberto Zucchini

摘要:

本文基于分次交换代数及其态射的抽象理论,给出了高阶规范理论和规范西格玛模型的纯代数形式。该公式结合了自然BRST对称性,也适用于AKSZ型结构。它还表明,一个完整的--成熟的BV配方,包括鬼自由度,更高的规范和规范西格玛模型领域必须被视为内部光滑功能的移位切丛的时空流形值在移位L_infty-代数体编码对称。与其他公式的关系,其中L_infty-代数胚产生于一个更高的李群胚李微分突出。

英文摘要:

In this paper, we present a purely algebraic formulation of higher gauge theory and gauged sigma models based on the abstract theory of graded commutative algebras and their morphisms. The formulation incorporates naturally BRST symmetry and is also suitable for AKSZ type constructions. It is also shown that for a full--fledged BV formulation including ghost degrees of freedom, higher gauge and gauged sigma model fields must be viewed as internal smooth functions on the shifted tangent bundle of a space time manifold valued in a shifted L_infty-algebroid encoding symmetry. The relationship to other formulations where the L_infty-algebroid arises from a higher Lie groupoid by Lie differentiation is highlighted.
