A-无穷代数的强同伦内积

Strong homotopy inner product of an A-infinity algebra

Cheol-Hyun Cho

摘要:

引入了A-无穷代数的循环对称内积的强同伦概念,并证明了Tradler的无穷内积形式中的一个特征定理.我们还证明了它等价于相应的形式非交换超流形上的非常数辛结构的概念。证明了循环滤子A-无穷代数的(开Gromov-Witten型)位势在循环滤子A-无穷同态下直到重新参数化、环化和常数加法都是不变的,推广了Kajiura的工作.

英文摘要:

We introduce a strong homotopy notion of a cyclic symmetric inner product of an A-infinity algebra and prove a characterization theorem in the formalism of the infinity inner products by Tradler. We also show that it is equivalent to the notion of a non-constant symplectic structure on the corresponding formal non-commutative supermanifold. We show that (open Gromov-Witten type) potential for a cyclic filtered A-infinity algebra is invariant under the cyclic filtered A-infinity homomorphism up to reparametrization, cyclization and a constant addition, generalizing the work of Kajiura.
