Starlike tree
open-in-new
<p>In the area of mathematics known as <a href="/facts/Graph_theory/VVPCd4TX">graph theory</a>, a <a href="/facts/Tree_(graph_theory)/TCWk4Joy">tree</a> is said to be starlike if it has exactly one vertex of <a href="/facts/Degree_(graph_theory)/LnFFpI8v">degree</a> greater than 2. This high-degree vertex is the root and a starlike tree is obtained by attaching at least three <a href="/facts/Path_graph/4Y2f35eM">linear graphs</a> to this central vertex. </p>
