Estimation and Inference in Large Heterogeneous Panels with a Multifactor Error Structure
, 2004
"... This paper presents a new approach to estimation and inference in panel data models with a multifactor error structure where the unobserved common factors are (possibly) correlated with exogenously given individualspecific regressors, and the factor loadings differ over the cross section units. The ..."

. The estimation procedure has the advantage that it can be computed by OLS applied to an auxiliary regression where the observed regressors are augmented by (weighted) cross sectional averages of the dependent variable and the individual specific regressors. Two different but related problems are addressed: one
Evidence for Invariants in Local Search
 IN PROCEEDINGS OF AAAI97
, 1997
"... It is well known that the performance of a stochastic local search procedure depends upon the setting of its noise parameter, and that the optimal setting varies with the problem distribution. It is therefore desirable to develop general priniciples for tuning the procedures. We present two statisti ..."

statistical measures of the local search process that allow one to quickly find the optimal noise settings. These properties are independent of the fine details of the local search strategies, and appear to be relatively independent of the structure of the problem domains. We applied these principles
Relative GromovWitten invariants
 Ann. of Math
, 2003
"... We define relative GromovWitten invariants of a symplectic manifold relative to a codimensiontwo symplectic submanifold. These invariants are the key ingredients in the symplectic sum formula of [IP4]. The main step is the construction of a compact space of ‘Vstable ’ maps. Simple special cases i ..."

Geometric invariant theory and flips
 Jour. AMS
, 1996
"... Ever since the invention of geometric invariant theory, it has been understood that the quotient it constructs is not entirely canonical, but depends on a choice: the choice of a linearization of the group action. However, the founders of the subject never made a systematic study of this dependence. ..."

Dependence on the spin structure of the eta and Rokhlin invariants
 Topology Appl
"... Abstract. We study the dependence of the eta invariant ηD on the spin structure, where D is a twisted Dirac operator on a (4k + 3)dimensional spin manifold. The difference between the eta invariants for two spin structures related by a cohomolgy class which is the reduction of a H 1 (M, Z)class is ..."

Let M (n) be a graph which is obtained from a path Pn or a cycle Cn by replacing each vertex by a fixed graph M and replacing each edge by a fixed set of edges joining the corresponding copies of M . A matrix approach to the computation of distance related invariants in such graphs is presented. T ..."

Secondary invariants and the . . .
, 1995
"... The Ruelle zetafunction of the geodesic flow on the sphere bundle S(X) of an evendimensional compact locally symmetric space X of rank 1 is a meromorphic function in the complex plane that satisfies a functional equation relating its values in s and −s. The multiplicity of its singularity in the ..."

Normal forms and invariant geometric structures for dynamical systems with invariant contracting foliations
 Math. Res. Letters
, 1998
"... Abstract. We present a certain version of the “non–stationary ” normal forms theory for extensions of topological dynamical systems (homeomorphisms of compact metrizable spaces) by smooth (C ∞ ) contractions of R n. The central concept is a notion of a sub–resonance relation which is an appropriate ..."

certain collection of inequalities between the relative rates of contraction in the fibers. One of the ways to formulate our first conclusion (the sub–resonance normal form theorem) is to say that there is a continuous invariant family of geometric structures in the fibers whose automorphism groups
Modular Invariance
, 2009
"... Two methods to prove the Riemann Hypothesis are presented. One is based on the modular properties of Θ (theta) functions and the other on the Hilbert–Polya proposal to find an operator whose spectrum reproduces the ordinates ρn (imaginary parts) of the zeta zeros in the critical line: sn = 1 +iρn. A ..."

. A detailed analysis of a onedimensional Diraclike 2 operator with a potential V (x) is given that reproduces the spectrum of energy levels En = ρn, when the boundary conditions ΨE(x = −∞) =±ΨE(x =+∞) areimposed. Such potential V (x) is derived implicitly from the relation x = x(V) = π (dN (V
