Add to ORKGABSTRACT. A formula for the determinant of the distance matrix for a tree as a function of the number of its vertices, independent of the structure of the tree, has been proven by several mathematicians. We explore the details of the proof by Weigen Yan and Yeong-NanYeh, look at the history of the topic, and see the theorem in action b
