In this paper, we establish the existence of a functional equation for a specific class of LC-functions. More precisely, we demonstrate that if the function $p_f(t):=f(t)(e^t-1)/t$, called the \\textit{modulator} of $L(s,f)$, exhibits even or odd symmetry, the \\textit{LC-function formula} -- a generalization of the Hurwitz formula -- naturally simplifies to a functional equation analogous to that of the Dirichlet L-function $L(s,\\chi)$, associated to a primitive character $\\chi$ of inherent parity. Furthermore, using this equation, we derive a general formula for the values of these LC-functions at even or odd positive integers, depending on whether the modulator $p_f$ is even or odd, respectively. Two illustrative examples of the functional equation are provided for distinct parity of modulators.", "revisions": [ { "version": "v1", "updated": "2024-09-01T19:04:38.000Z" } ], "analyses": { "subjects": [ "11M41" ], "keywords": [ "functional equation", "odd modulator", "lc-functions", "hurwitz zeta function", "distinct parity" ], "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable" } } }
