We set up an explicit formula for the fundamental solution. We show that we can represent any solution to the homogeneous Klein-Gordon equation on the torus as finite sum over generalized 3-fold periodic elliptic functions that are in the kernel of the Klein-Gordon operator. Furthermore we prove Cauchy and Green type integral formulas and set up a Teodorescu and Cauchy transform for the toroidal Klein-Gordon operator. These in turn are used to set up explicit formulas for the solution to the inhomogeneous version of the Klein-Gordon equation on the 3-torus.}, issn = {1611-4086}, doi = {10.25643/bauhaus-universitaet.2863}, url = {https://www.db-thueringen.de/receive/dbt_mods_00037103}, url = {https://doi.org/10.25643/bauhaus-universitaet.2863}, file = {:https://www.db-thueringen.de/servlets/MCRFileNodeServlet/dbt_derivate_00043253/8-final-man_106_pdfa.pdf:PDF}, language = {en} }
