curved A-infinity algebra

Contents

Idea

A curved A A_\infty is defined just like an A-infinity algebra, but allowing in the definition also a 0-ary operation. m 0m_0. Including this means thte unary operation no longer squares to 0 but to be proportinal to the binary product with this constant

m 1m 1m 2(m 0,). m_1 \circ m_1 \propto m_2(m_0,-) \,.

This m 0m_0 is called the curvature of the curved A A_\infty-algebra.
