量子开闭同伦代数与弦场论

Quantum Open-Closed Homotopy Algebra and String Field Theory

Korbinian Muenster, Ivo Sachs

摘要:

我们用同伦代数重新表述了兹维巴赫量子开闭弦场论的代数结构。我们称之为量子开闭同伦代数(QOCHA),它是Kajiura和Stasheff的开闭同伦代数(OCHA)的推广。同伦公式揭示了闭弦背景对开弦场论变形的新认识。特别是,量子闭同伦代数的毛雷尔嘉当元素的变形定义了相容的量子开弦场论。

英文摘要:

We reformulate the algebraic structure of Zwiebach's quantum open-closed string field theory in terms of homotopy algebras. We call it the quantum open-closed homotopy algebra (QOCHA) which is the generalization of the open-closed homotopy algebra (OCHA) of Kajiura and Stasheff. The homotopy formulation reveals new insights about deformations of open string field theory by closed string backgrounds. In particular, deformations by Maurer Cartan elements of the quantum closed homotopy algebra define consistent quantum open string field theories.
