. This approach refines results relating the spectral gap of a graph to the so-called magnification of a graph. A concentration result involving is also derived. 
Expansion And Isoperimetric Constants For Product Graphs
TLDR
Vertex and edge isoperimetric constants of graphs are studied using a functional-analytic approach and the growth properties of these constants is analyzed.
Isoperimetric Invariants For Product Markov Chains and Graph Products
Bounds on some isoperimetric constants of the Cartesian product of Markov chains are obtained in terms of related isoperimetric quantities of the individual chains.
Surface measures and related functional inequalities on configuration spaces
Using finite difference operators, we define a notion of boundary and surface measure for configuration sets under Poisson measures. A Margulis-Russo type identity and a co-area formula are stated
Concentration of Measure for Products of Markov Kernels and Graph Products via Functional Inequalities
We present versions of concentration inequalities for products of Markov kernels and graph products. We also present discussions of a variety of consequences such as sharp upper bounds, in terms of
Surveys in Differential Geometry
The purpose of this article is to survey the recent progress made on estimating positive eigenvalues of Laplacian on hyperbolic Riemann surfaces in the case of congruence subgroups in connection with
Sharp edge, vertex, and mixed Cheeger type inequalities for finite Markov kernels
We show how the evolving set methodology of Morris and Peres can be used to show Cheeger inequalities for bounding the spectral gap of a finite Markov kernel. This leads to sharp versions of several

Multi-Way Expanders and Imprimitive Group Actions on Graphs
For n at least 2, the concept of n-way expanders was defined by various researchers. Bigger n gives a weaker notion in general, and 2-way expanders coincide with expanders in usual sense. Koji

Poincaré’s inequalities and Talagrand’s concentration phenomenon for the exponential distribution
Summary. We present a simple proof, based on modified logarithmic Sobolev inequalities, of Talagrand’s concentration inequality for the exponential distribution. We actually observe that every

An Asymptotic Isoperimetric Inequality
Abstract. For a finite metric space V with a metric $ \rho $, let V n be the metric space in which the distance between (a1, . . ., an) and (b1, . . ., bn) is the sum $ \sum^{n}_{i = 1} \rho (a_i,
