Algebraic and geometric characterizations related to the quantization problem of the $$C_{2,8}$$ channel

Abstract

In this paper, we consider the steps to be followed in the analysis and interpretation of the quantization problem related to the \(C_{2,8}\) channel, where the Fuchsian differential equations, the generators of the Fuchsian groups, and the tessellations associated with the cases \(g=2\) and \(g=3\), related to the hyperbolic case, are determined. In order to obtain these results, it is necessary to determine the genus g of each surface on which this channel may be embedded. After that, the procedure is to determine the algebraic structure (Fuchsian group generators) associated with the fundamental region of each surface. To achieve this goal, an associated linear second-order Fuchsian differential equation whose linearly independent solutions provide the generators of this Fuchsian group is devised. In addition, the tessellations associated with each analyzed case are identified. These structures are identified in four situations, divided into two cases \((g=2\) and \(g=3)\), obtaining, therefore, both algebraic and geometric characterizations associated with quantizing the \(C_{2,8}\) channel.
