Abstract
The Casimir energy for the transverse oscillations of piecewise uniform bos onic strings with either untwisted or twisted continuous conditions is disc ussed. After calculating the analytic values of zeros of the dispersion fun ction under certain conditions, we obtain the Casimir energy for both open and closed bosonic strings composed of two or three segments.
