Consider the Dirichlet problem u= 0 in , with the boundary conditions u 0 on @D and u(0) = 1. Suppose that there exists a solution. Then uis harmonic in , and continuous in D with u(0) = 1. WebSep 22, 2024 · In this section, we give the estimate for the scale-invariant Cassinian metric in the unit disk or the upper half plane by studying the formulas of special cases and the geometry of the \({\tilde{\tau }}\)-metric.The results can be applied to higher-dimensional cases, e.g., the special formulas are used in the proof of the results in Sects. 4 and 5. Webof unit disk graphs is an NP-hard problem, we show that the problem of nding unit disk graph coordinates given a graph G = (V;E) is NP-hard. Subsequently, we show that the proof does not extend to quasi unit disk graphs, a generalization of unit disk graphs.
