Abstract It is well known that the second-order cone and the circular cone have many analogous properties. In particular, there exists an important distance inequality associated with the second-order cone and the circular cone. The inequality indica

A set of lines through the origin in Euclidean space is called equiangular when any pair of lines from the set intersects with each other at a common angle. We study the maximum size of equiangular lines in Euclidean space and use graph theoretic app

In this paper we show that the conjecture of Lemmens and Seidel of 1973 for systems of equiangular lines with common angle arccos ( 1 / 5 ) is true. Our main tool is forbidden subgraphs for smallest Seidel eigenvalue −5.

A permutation of the multiset { 1 , 1 , 2 , 2 , … , n , n } is called a Stirling permutation of order n if every entry between the two occurrences of i is greater than i for each i ∈ { 1 , 2 , … , n } . In this paper, we introduce the definitio

In this short paper, we look into a conclusion drawn by Alzalg (J Optim Theory Appl 169:32---49, 2016). We think the conclusion drawn in the paper is incorrect by pointing out three things. First, we provide a counterexample that the proposed inner p

In this paper, we introduce the definitions of simsun succession statistics and simsun patterns. In addition to its original definition by Brenti, we give two more combinatorial interpretations of the $q$-Eulerian polynomials using simsun successions

In this paper, claims by Lemmens and Seidel in 1973 about equiangular sets of lines with angle 1 ∕ 5 are proved by carefully analyzing pillar decomposition, with the aid of the uniqueness of two-graphs on 276 vertices. The Neumann Theorem is genera
