Interference mitigation through limited receiver cooperation: Symmetric case
 IEEE TRANSACTIONS ON INFORMATION THEORY
, 2009
"... Interference is a major issue that limits the performance in wireless networks, and the cooperation among receivers can help mitigate interference by forming distributed MIMO systems. The rate at which receivers cooperate, however, is limited in most scenarios. How much interference can one bit of ..."

of the symmetric capacity in the symmetric setup. We propose strategies achieving the symmetric capacity universally to within 3 bits. The strategy consists of two parts: (1) the transmission scheme, where superposition encoding with a simple power split is employed, and (2) the cooperative protocol, where
The Variance Gamma Process and Option Pricing.
 European Finance Review
, 1998
"... : A three parameter stochastic process, termed the variance gamma process, that generalizes Brownian motion is developed as a model for the dynamics of log stock prices. The process is obtained by evaluating Brownian motion with drift at a random time given by a gamma process. The two additional par ..."

densities are estimated for data on the S&P500 Index and the prices of options on this Index. It is observed that the statistical density is symmetric with some kurtosis, while the risk neutral density is negatively skewed with a larger kurtosis. The additional parameters also correct for pricing biases
Sharp linear and bilinear restriction estimates for the paraboloid in the cylindrically symmetric case
, 2007
"... In this paper, for cylindrically symmetric functions dyadically supported on the paraboloid, we obtain a family of sharp linear and linear adjoint restriction estimates. As corollaries of them, for such functions, we first extend the ranges of exponents for the classical linear or bilinear adjoint ..."

Monte Carlo simulation of macroeconomic risk with a continuum of agents: The symmetric case
 ECONOMIC THEORY
, 2003
"... In large random economies with heterogeneous agents, a standard stochastic framework presumes a random macro state, combined with idiosyncratic micro shocks. This can be formally represented by a random process consisting of a continuum of random variables that are conditionally independent given th ..."

In large random economies with heterogeneous agents, a standard stochastic framework presumes a random macro state, combined with idiosyncratic micro shocks. This can be formally represented by a random process consisting of a continuum of random variables that are conditionally independent given the macro state. However, this process satisfies a standard joint measurability condition only if there is essentially no idiosyncratic risk at all. Based on iteratively complete product measure spaces, we characterize the validity of the standard stochastic framework via Monte Carlo simulation as well as eventwise measurable conditional probabilities. These general characterizations also allow us to strengthen some earlier results related to exchangeability and independence.
Equilibria in repeated games of incomplete information: The general symmetric case

UNIVERSALITY OF LOWENERGY SCATTERING IN 2 + 1 DIMENSIONS: THE NON SYMMETRIC CASE
, 2004
"... For a very large class of potentials, V (⃗x), ⃗x ∈ R 2, we prove the universality of the low energy scattering amplitude, f ( ⃗ k ′ , ⃗ k). The result is f = √ π 2 {1/log k) + O(1/(log k)2). The only exceptions occur if V happens to have a zero energy bound state. Our new result includes as a spe ..."
