Twisted de Rham Theory for String Double Copy in AdS
Analysis
Key Takeaways
- •Proves the double-copy relationship between open- and closed-string amplitudes in AdS space.
- •Uses a new, noncommutative version of twisted de Rham theory.
- •Provides a mathematical foundation for understanding the relationship between string amplitudes in AdS.
- •Extends the double-copy framework from flat space to AdS space.
“The inverse of this intersection number is precisely the AdS double-copy kernel for the four-point open- and closed-string generating functions.”
