Ambarzumian’s Theorem for Trees
نویسندگان
چکیده
The classical Ambarzumian’s Theorem for Schrödinger operators −D2 + q on an interval, with Neumann conditions at the endpoints, says that if the spectrum of (−D2 + q) is the same as the spectrum of (−D2) then q = 0. This theorem is generalized to Schrödinger operators on metric trees with Neumann conditions at the boundary vertices.

Limit distribution of the degrees in scaled attachment random recursive trees
We study the limiting distribution of the degree of a given node in a scaled attachment random recursive tree, a generalized random recursive tree, which is introduced by Devroye et. al (2011). In a scaled attachment random recursive tree, every node $i$ is attached to the node labeled $lfloor iX_i floor$ where $X_0$, $ldots$ , $X_n$ is a sequence of i.i.d. random variables, with support in [0,...
متن کاملSperner and Kkm-type Theorems on Trees and Cycles
In this paper we prove a new combinatorial theorem for labellings of trees, and show that it is equivalent to a KKM-type theorem for finite covers of trees and to discrete and continuous fixed point theorems on finite trees. This is in analogy with the equivalence of the classical Sperner’s lemma, KKM lemma, and the Brouwer fixed point theorem on simplices. Furthermore, we use these ideas to de...

متن کاملDual Ramsey Theorem for Trees
The classical Ramsey theorem was generalized in two major ways: to the dual Ramsey theorem, by Graham and Rothschild, and to Ramsey theorems for trees, initially by Deuber and Leeb. Bringing these two lines of thought together, we prove the dual Ramsey theorem for trees. Galois connections between partial orders are used in formulating this theorem, while the abstract approach to Ramsey theory,...
متن کاملParikh’s theorem
This chapter will discuss Parikh’s theorem and provide a proof for it. The proof is done by induction over a set of derivation trees, and using the Parikh mappings obtained from the set of terminal derivation trees and the possible enlargement of them during derivation. Moreover, the usefulness of the theorem will be lightly addressed.
