The Casimir effect for pistons with transmittal boundary conditions [PDF]
Int. J. Mod. Phys. A, 32, 1750182 (2017), 2017 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.

Measure solutions of one-dimensional piston problem for compressible Euler equations of Chaplygin gas [PDF]
arXiv, 2019 We are concerned with the one-dimensional piston problem for the compressible Euler equations of Chaplygin gas. If the piston moves at constant subsonic speed to the uniform gas, there exists an integral weak solution for the piston problem, consisting of a shock separating constant states ahead of the piston.
