Directionally Convex Ordering of Random Measures, Shot Noise Fields and Some Applications to Wireless Communications [PDF]

, 2009
Directionally convex ($dcx$) ordering is a tool for comparison of dependence structure of random vectors that also takes into account the variability of the marginal distributions.

N=2 supersymmetric Yang-Mills theories and Whitham integrable hierarchies

, 1999
We review recent work on the study of N=2 super Yang-Mills theory with gauge group SU(N) from the point of view of the Whitham hierarchy, mainly focusing on three main results: (i) We develop a new recursive method to compute the whole instanton ...

Singular Continuous Spectrum for the Laplacian on Certain Sparse Trees

, 2006
We present examples of rooted tree graphs for which the Laplacian has singular continuous spectral measures. For some of these examples we further establish fractional Hausdorff dimensions.

Jacobi Identity for Vertex Algebras in Higher Dimensions

, 2005
Vertex algebras in higher dimensions provide an algebraic framework for investigating axiomatic quantum field theory with global conformal invariance.

Block-diagonal reduction of matrices over commutative rings I. (Decomposition of modules vs decomposition of their support)

, 2020
Consider rectangular matrices over a commutative ring R. Assume the ideal of maximal minors factorizes, I_m(A)=J_1*J_2. When is A left-right equivalent to a block-diagonal matrix? (When does the module/sheaf Coker(A) decompose as the corresponding direct

Unifying quantization for inhomogeneous integrable models

, 2005
Integrable inhomogeneous versions of the models like NLS, Toda chain, Ablowitz-Ladik model etc., though well known at the classical level, have never been investigated for their possible quantum extensions.

Raising and lowering operators and their factorization for generalized orthogonal polynomials of hypergeometric type on homogeneous and non-homogeneous lattice

, 2004
We complete the construction of raising and lowering operators, given in a previous work, for the orthogonal polynomials of hypergeometric type on non-homogeneous lattice, and extend these operators to the generalized orthogonal polynomials, namely ...

10 + 1 to 3 + 1 in an Early Universe with mutually BPS Intersecting Branes

, 2010
We assume that the early universe is homogeneous, anisotropic, and is dominated by the mutually BPS 22'55' intersecting branes of M theory. The spatial directions are all taken to be toroidal.

Dynamics on geometrically finite hyperbolic manifolds with applications to Apollonian circle packings and beyond [PDF]

, 2010
We present recent results on counting and distribution of circles in a given circle packing invariant under a geometrically finite Kleinian group and discuss how the dynamics of flows on geometrically finite hyperbolic $3$ manifolds are related.
