Asymptotic Symmetries in Gravitational Theory
Physical Review, 1962It is pointed out that the definition of the inhomogeneous Lorentz group as a symmetry group breaks down in the presence of gravitational fields even when the dynamical effects of gravitational forces are completely negligible. An attempt is made to rederive the Lorentz group as an "asymptotic symmetry group" which leaves invariant the form of the ...

Unit‐Root Asymptotic Theories (II)
1996Abstract This chapter brings together three unrelated topics of asymptotic theories. It presents a mathematical analysis of tests on the case where {Δxt} is i.i.d., possibly with a non-zero mean. It explains the mathematics used for the case where {Δxt} is serially correlated.

Simulated Asymptotic Least Squares Theory [PDF]
, 2000 We develop in this paper a general econometric methodology referred to as the Simulated Asymptotic Least Squares (SALS). It is shown that this approach provides a unifying theory for 'approximation-based' or simulation-based inference methods and nests the Simulated Nonlinear Least Squares (SSNLS), the Simulated Pseudo Maximum Likelihood (SPML), the ...

The assumptions of the asymptotic method of a narrow reaction zone in a gas heating wave are considered. Using the known laws of heat and mass transfer in a gaseous medium in which chemical reactions can take place, it is proved that the assumptions of the narrow reaction zone method contradict the laws of conservation of energy and mass.
