Laplacian spectrum of the unit graph associated to the ring of integers modulo pq

Laplacian spectrum of the unit graph associated to the ring of integers modulo pq

Let $ R $ be a ring and $ U(R) $ be the set of unit elements of $ R $. The unit graph $ G(R) $ of $ R $ is the graph whose vertices are all the elements of $ R $, defining distinct vertices $ x $ and $ y $ to be adjacent if and only if $ x + y \in U(R) $. The Laplacian spectrum of $ G(\mathbb{Z}_n)...
