abstract
In this paper we discuss the BFK type gluing formula for zeta-determinants of Laplacians with respect to the Robin boundary condition on a compact Riemannian manifold. As a special case, we discuss the gluing formula with respect to the Neumann boundary condition. We also compute the difference of two zeta-determinants with respect to the Robin and Dirichlet boundary conditions. We use this result to compute the zeta-determinant of a Laplacian on a cylinder when the Robin boundary condition is imposed, which extends a result in [25]. We also discuss the gluing formula more precisely when the product structure is given near a cutting hypersurface.
