Query: The Casimir effect for pistons with transmittal boundary conditions   This work focuses on the analysis of the Casimir effect for pistons subject
to transmittal boundary conditions. In particular we consider, as piston
configuration, a direct product manifold of the type $I\times N$ where $I$ is a
closed interval of the real line and $N$ is a smooth compact Riemannian
manifold. By utilizing the spectral zeta function regularization technique, we
compute the Casimir energy of the system and the Casimir force acting on the
piston. Explicit results for the force are provided when the manifold $N$ is a
$d$-dimensional ball.
