On the Complexity of Matroid Isomorphism Problem
Raghavendra Rao B. V., Jayalal M. N. Sarma
We study the complexity of testing if two given matroids are isomorphic. The problem is easily seen to be in . In the case of linear matroids, which are represented over pol…
Tight Approximation Ratio of a General Greedy Splitting Algorithm for the Minimum k-Way Cut Problem
Mingyu Xiao, Leizhen Cai, Andrew C. Yao
For an edge-weighted connected undirected graph, the minimum -way cut problem is to find a subset of edges of minimum total weight whose removal separates the graph into con…
Hamiltonian Structures and Reciprocal Transformations for the -KdV-CH Hierarchy
Ming Chen, Si-Qi Liu, Youjin Zhang
The -KdV-CH hierarchy is a generalization of the Korteweg-de Vries and Camassa-Holm hierarchies parametrized by constants. In this paper we clarify some properties of its…
Ancilla-Assisted Discrimination of Quantum Gates
Jianxin Chen, Mingsheng Ying
The intrinsic idea of superdense coding is to find as many gates as possible such that they can be perfectly discriminated. In this paper, we consider a new scheme of discriminatio…
General Sum Rules for WW Scattering in Higgsless Models: Equivalence Theorem and Deconstruction Identities
R. Sekhar Chivukula, Hong-Jian He, Masafumi Kurachi +2
We analyze inelastic 2 to 2 scattering amplitudes for gauge bosons and Nambu-Goldstone bosons in deconstructed Higgsless models. Using the (KK) Equivalence Theorem in 4D (5D), we d…
Mutual information is copula entropy
Jian Ma, Zengqi Sun
We prove that mutual information is actually negative copula entropy, based on which a method for mutual information estimation is proposed.
