Normal Subgroup Growth of Linear Groups: the (G2; F4;E8)-Theorem
Michael Larsen, Alexander Lubotzky
Let G be a finitely generated group and M_n(G) the number of its normal subgroup subgroups of index at most n. For linear groups G we show that M_n(G) can grow polynomially in n on…
Algebraic logic and logically-geometric types in varieties of algebras
Boris Plotkin, Elena Aladova, Eugene Plotkin
The main objective of this paper is to show that the notion of type which was developed within the frames of logic and model theory has deep ties with geometric properties of algeb…
Efficient and Accurate Gaussian Image Filtering Using Running Sums
Elhanan Elboher, Michael Werman
This paper presents a simple and efficient method to convolve an image with a Gaussian kernel. The computation is performed in a constant number of operations per pixel using runni…
Ice-Creams and Wedge Graphs
Eyal Ackerman, Tsachik Gelander, Rom Pinchasi
What is the minimum angle such that given any set of -directional antennas (that is, antennas each of which can communicate along a wedge of angle ), one can always ass…
Sieve methods in group theory I: Powers in Linear groups
Alexander Lubotzky, Chen Meiri
A general sieve method for groups is formulated. It enables one to "measure" subsets of a finitely generated group. As an application we show that if is a finitely generated no…
Concurrent Auctions Across The Supply Chain
M. Babaioff, N. Nisan
With the recent technological feasibility of electronic commerce over the Internet, much attention has been given to the design of electronic markets for various types of electroni…
