Euler's formula for the sphere. Roughly speaking, a network (or, as mathematicians would say, a graph) is a collection of points, called vertices, and lines joining them, called edges.Each edge meets only two vertices (one at each of its ends), and two edges must not intersect except at a vertex (which will then be a common endpoint of the two edges).Leonhard Euler was a Swiss Mathematician and Physicist, and is credited with a great many pioneering ideas and theories throughout a wide variety of areas and disciplines. One such area was graph theory. Euler developed his characteristic formula that related the edges (E), faces(F), and vertices(V) of a planar graph,The Criterion for Euler Paths Suppose that a graph has an Euler path P. For every vertex v other than the starting and ending vertices, the path P enters v thesamenumber of times that itleaves v (say s times). Therefore, there are 2s edges having v as an endpoint. Therefore, all vertices other than the two endpoints of P must be even vertices.

A product xy x y is even iff at least one of x, y x, y is even. A graph has an eulerian cycle iff every vertex is of even degree. So take an odd-numbered vertex, e.g. 3. It will have an even product with all the even-numbered vertices, so it has 3 edges to even vertices. It will have an odd product with the odd vertices, so it does not have any ...Finally we present Euler’s theorem which is a generalization of Fermat’s theorem and it states that for any positive integer m m that is relatively prime to an integer a a, aϕ(m) ≡ 1(mod m) (3.5.1) (3.5.1) a ϕ ( m) ≡ 1 ( m o d m) where ϕ ϕ is Euler’s ϕ ϕ -function. We start by proving a theorem about the inverse of integers ...Graph theory is a branch of mathematics started by Euler [] as early as 1736.It took a hundred years before the second important contribution of Kirchhoff [] had been made for the analysis of electrical networks.Cayley [] and Sylvester [] discovered several properties of special types of graphs known as trees.Poincaré [] defined in …

These circuits and paths were first discovered by Euler in 1736, therefore giving the name “Eulerian Cycles” and “Eulerian Paths.”Leonard Euler solved it in 1735 which is the foundation of modern graph theory. Euler’s solution for Konigsberg Bridge Problem is considered as the first theorem of Graph Theory which gives the idea of Eulerian circuit. It can be used in several cases for shortening any path.

In modern graph theory, an Eulerian path traverses each edge of a graph once and only once. Thus, Euler’s assertion that a graph possessing such a path has at most two vertices of odd degree was the first theorem in graph theory. Graph Theory is a relatively new area of mathematics, first studied by the super famous mathematician Leonhard Euler in 1735. Since then it has blossomed in to a powerful tool used in nearly every branch of science and is currently an active area of mathematics research. The problem above, known as the Seven Bridges of Königsberg, is the ...
