Webb4 juli 2024 · In this paper, we study roots of the total domination polynomial of some graphs. We show that all roots of Dt ( G, x) lie in the circle with center (–1, 0) and radius , where d is the minimum degree of G. As a consequence, we prove that if , then every integer root of Dt ( G, x) lies in the set {–3, –2, –1, 0}.

Webb26 apr. 2015 · A rooted tree is a fully connected, acyclic graph with a special node that is called the root of the tree. You may have studied rooted trees in your data structures class. With a root, it is possible to define a parent and children for each node. But without a root, we will regard the tree simply as a connected, acyclic graph. Examples WebbThe roots function calculates the roots of a single-variable polynomial represented by a vector of coefficients. For example, create a vector to represent the polynomial , then calculate the roots. p = [1 -1 -6]; r = roots (p) r = 3 -2. By convention, MATLAB ® returns the roots in a column vector.

WebbThis quadratic equation root calculator lets you find the roots or zeroes of a quadratic equation. A quadratic is a second degree polynomial of the form: ax2 + bx + c = 0 where a ≠ 0. To solve an equation using the online calculator, simply enter the math problem in the text area provided. Hit the calculate button to get the roots. A special case of interest are rooted trees, the trees with a distinguished root vertex. If the directed paths from the root in the rooted digraph are additionally restricted to be unique, then the notion obtained is that of (rooted) arborescence—the directed-graph equivalent of a rooted tree. A rooted graph contains an arborescence with the same root if and only if the whole graph can be reached from the root, and computer scientists have studied algorithmic problems of finding optimal arb…
