A dimension reduction technique for estimation in linear mixed models

This paper proposes a dimension reduction technique for estimation in linear mixed models. Specifically, we show that in a linear mixed model, the maximum-likelihood (ML) problem can be rewritten as a substantially simpler optimization problem which presen ...

Limit laws of transient excited random walks on integers

Thomas Mountford

We consider excited random walks (ERWs) on Z with a bounded number of i.i.d. cookies per site without the non-negativity assumption on the drifts induced by the cookies. Kosygina and Zerner [15] have shown that when the total expected drift per site, delta ...

Overlap properties of geometric expanders

The overlap number of a finite (d + 1)-uniform hypergraph H is the largest constant c(H) is an element of (0, 1] such that no matter how we map the vertices of H into R-d, there is a point covered by at least a c(H)-fraction of the simplices induced by the ...

On Decentralized Navigation Schemes for Coordination of Multi-Agent Dynamical Systems

Denis Gillet

Coordination of autonomous non-point agents in four-way crossings is studied in this work. A control scheme based on artiﬁcial potential functions is proposed in order to coordinate holonomic agents whose aim is to pass through an intersection while avoidi ...

Convolution Operators And Homomorphisms Of Locally Compact Groups

Let 1 < p < infinity, let G and H be locally compact groups and let c) be a continuous homomorphism of G into H. We prove, if G is amenable, the existence of a linear contraction of the Banach algebra CVp (G) of the p-convolution operators on G into CVp (H ...
