On the edit distance from $K_{2,t}$-free graphs I: Cases $t=3,4$
edit distance quadratic programming strongly regular graphs
2011/1/18
The edit distance between two graphs on the same vertex set is defined to be size of the symmetric difference of their edge sets. The edit distance function of a hereditary property, H,is a function o...
In this paper, we generalize the usual notions of waves, fronts and propagation speeds in a very general setting. These new notions, which cover all usual situations,involve uniform limits, with respe...
In programming language semantics, it has proved to be fruitful to analyze context-dependent notions of computation, e.g., dataflow computation and attribute grammars, using comonads.
Spectrum is the most valuable resource in the communication system, but unfor-tunately, so far, a half of the spectrum has been wasted, that is negative frequency spectrum.
Network MIMO with Linear Zero-Forcing Beamforming: Large System Analysis, Impact of Channel Estimation and Reduced-Complexity Scheduling
Linear Zero-Forcing Beamforming Large System Analysis Impact of Channel Estimation Reduced-Complexity Scheduling
2011/2/21
We consider the downlink of a multi-cell system with multi-antenna base stations and single-antenna user terminals, arbitrary base station cooperation clusters, distance-dependent propagation pathloss...
Base change for Bernstein centers of depth zero principal series blocks
Base change Bernstein centers depth zero principal series blocks
2011/2/25
Let G be an unramified group over a p-adic field. This article intro-duces a base change homomorphism for Bernstein centers of depth-zero principal series blocks for G and proves the corresponding bas...
Artin-Tate motivic sheaves with finite coefficients over a smooth variety
Artin-Tate motivic finite coefficients smooth variety
2011/2/22
We propose a construction of a tensor exact category Fm X of Artin–Tate motivic sheaves with finite coefficients Z/m over a smooth variety X (over a field K of characteristic prime to m) in terms of &...
Let R be a noetherian commutative ring, and F : · · · → F2 → F1 → F0 → 0 a complex of flat R-modules. We prove that if (p) ⊗R F is acyclic for every p ∈ SpecR, then F is acyclic, and H0(F) is R...
Fast and accurate con-eigenvalue algorithm for optimal rational approximations
Fast accurate con-eigenvalue algorithm optimal rational approximations
2011/2/21
The need to compute small con-eigenvalues and the associated con-eigenvectors of
positive-definite Cauchy matrices naturally arises when constructing rational approximations with an optimally small L...
Perturbations of Banach algebras and amenability
Perturbations of Banach algebras amenability
2011/1/19
In this paper we prove that if (A, π) is an amenable Banach algebra and if ρ is another Banach algebra multiplication on A such that kρ−πk < 1 11 , then (A, ρ) is also amenable.

We show that for a Banach algebra A with a bounded approximate identity, the amenability of Ab⊗A, the amenability of Ab⊗Aop and the amenability of A are equivalent. Also if A is a closed i...
Contact Homology of Orbit Complements and Implied Existence
Contact Homology of Orbit Complements Implied Existence
2011/1/19
For Reeb vector elds on closed 3-manifolds, cylindrical contact homology is used to show that the existence of a set of closed Reeb orbit with certain knotting/linking properties implies the existenc...
We identify the finite list of minimal analytic n-gaps which are not weakly countably separated, and we prove that every analytic n-gap which is not countably separated contains a gap from our finite ...
Throughput and Latency of Acyclic Erasure Networks with Feedback in a Finite Buffer Regime
Throughput Latency of Acyclic Erasure Networks Feedback Finite Buffer Regime
2011/1/21
The exact Markov modeling analysis of erasure networks with finite buffers is an extremely hard problem due to the large number of states in the system. In such networks,packets are lost due to either...
