A Polytope Combinatorics for Semisimple Groups
Algebraic cross homology of the cycle cycle the image
2014/12/29
Mirkovi and Vilonen discovered a canonical basis of algebraic cycles for the intersection homology of (the closures of the strata of) the loop Grassmannian. The moment map images of these varieties ar...
Component groups of unipotent centralizers in good characteristic
Algebraically closed field is good conjugacy classes group conjugacy classes
2014/12/29
Let G be a connected, reductive group over an algebraically closed field of good characteristic. For uG unipotent, we describe the conjugacy classes in the component group A(u) of the centralizer of u...
Robert MacPherson and arithmetic groups
Robert macpherson theory algorithm modular locally symmetric space structure
2014/12/25
We survey contributions of Robert MacPherson to the theory of arithmetic groups. There are two main areas we discuss: (i) explicit reduction theory for Siegel modular threefolds, and (ii) construction...
Let be an affine Weyl group, and let be a left, right, or two-sided Kazhdan-Lusztig cell in . Let be the set of all reduced expressions of elements of , regarded as a formal language in the sense of t...
PIECES OF NILPOTENT CONES FOR CLASSICAL GROUPS
Nilpotent cone orbit nilpotent cone the number of dollars
2014/12/24
We compare orbits in the nilpotent cone of type $B_n$, that of type $C_n$, and Kato's exotic nilpotent cone. We prove that the number of $\F_q$-points in each nilpotent orbit of type $B_n$ or $C_n$ eq...
Explaining temporal trends in annualized relapse rates in placebo groups of randomized controlled trials in relapsing multiple sclerosis: systematic review and meta-regression
multiple sclerosis relapses annualized relapse rates placebo baseline characteristics eligibility criteria meta-analysis meta-regression systematic review
2013/4/27
Background: Recent studies have shown a decrease in annualised relapse rates (ARRs) in placebo groups of randomised controlled trials (RCTs) in relapsing multiple sclerosis (RMS).
Methods: We conduc...

The main focus of this work is on developing models for the ac-tivity profile of a terrorist group, detecting sudden spurtsand down-falls in this profile, and in general, tracking it over a period of ...
Estimating a Causal Order among Groups of Variables in Linear Models
Causal Order among Groups Variables in Linear Models
2012/9/19
The machine learning community has recently devoted much attention to the problem of inferring causal relationships from statistical data. Most of this work has focused on uncovering connections among...
Statistical Distribution of Crystallographic Groups for Inorganic Crystal Structure Database
Statistical Distribution Crystallographic Groups Inorganic Crystal Structure Database
2011/7/6
We introduce a method that defines the species (representatives) of inorganic compounds, and studied the statistical distribution of the defined species among space groups (distribution of space group...
Statistics of statisticians: Critical mass of statistics and operational research groups in the UK
Critical mass of statistics operational research groups statisticians
2011/3/24
Using a recently developed model, inspired by mean field theory in statistical physics, and data from the UK's Research Assessment Exercise, we analyse the relationship between the quality of statisti...
Infinite Hierarchical MMSB Model for Nested Communities/Groups in Social Networks
Infinite Hierarchical MMSB Model Nested Communities/Groups Social Networks
2010/10/19
Actors in realistic social networks play not one but a number of diverse roles depending on whom they interact with, and a large number of such role-specific interactions collectively determine social...

2009/9/22
Within the rapidly developing theory 01 random limit
theory for real-valued random variables the concepts of geometric
convolution and geometric stability play a fundamental role. In several

Laws of large numbers on simply connected step 2-nilpotent Lie groups
Laws of large numbers step 2-nilpotent Lie groups
2009/9/22
The Strong Law of Large Numbers due to Marcinkiewicz
and Zygmund is carried over to simply connected step 2-nilpotent
Lie groups. Moreover, for such groups, we prove analogues of the
classical theo...
