The GHY boundary term from the string worldsheet to linear order
Amr Ahmadain, Shoaib Akhtar, Rifath Khan
Using the method of images we derive the boundary term of the Einstein- action in half-space from the spherical worldsheet to first order in and to linear order in the…

A Worldsheet Derivation of the Classical Off-shell Boundary Action for the Dilaton in Half-Space
Amr Ahmadain, Rifath Khan
We use the method of images to present a worldsheet derivation of the sphere partition function for the dilaton in half-space to leading order in with Neumann boundary condit…
