http://homepages.math.uic.edu/~kauffman/RobbinsPaper.pdf In graph theory, Robbins' theorem, named after Herbert Robbins (1939), states that the graphs that have strong orientations are exactly the 2-edge-connected graphs. That is, it is possible to choose a direction for each edge of an undirected graph G, turning it into a directed graph that has a path from every vertex … See more Robbins' characterization of the graphs with strong orientations may be proven using ear decomposition, a tool introduced by Robbins for this task.

WebOct 27, 2024 · This chapter has as its focus Robin's theorem, an explicit inequality involving the sum-of-divisors function, valid on an explicit range, its validity being equivalent to RH. It forms part of what we call the Ramanujan–Robincriterion. We include Ramanujan because this great Indian mathematician first demonstrated the truth of the inequality ... WebRobbins’ theorem [Robbins, Am. Math. Monthly, 1939] states that such an orientation exists if and only if the graph is 2-edge connected. A natural extension of this problem is the following: Suppose that the edges of the graph is partitioned into trails.

WebThis is Robin's theorem and the inequality became known after him. Robin furthermore showed that if the Riemann hypothesis is false then there are an infinite number of values of n that violate the inequality, and it is known that the smallest such n > 5040 must be superabundant ( Akbary & Friggstad 2009 ). Robbins (1939) introduces the problem of strong orientation with a story about a town, whose streets and intersections are represented by the given graph G. According to Robbins' story, the people of the town want to be able to repair any segment of road during the weekdays, while still allowing any part of the town to be reached from any other part using the remaining roads as two-way streets. On the weekends, all roads are open, but because of heavy traffic volume, they wis…
