Critical (φ 4)3, Ǫ
The Euclidean (φ)3, ǫ model in R 3 corresponds to a perturbation by a φ interaction of a Gaussian measure on scalar fields with a covariance depending on a real parameter ε in the range 0 ≤ ε ≤ 1. For ε = 1 one recovers the covariance of a massless scalar field in R. For ε = 0 φ is a marginal interaction. For 0 ≤ ε < 1 the covariance continues to be Osterwalder-Schrader and pointwise positive. ...
متن کاملnoncommutative φ 3 model in 4 dimensions
We study the quantization of the noncommutative selfdual φ model in 4 dimensions, by mapping it to a Kontsevich model. The model is shown to be renormalizable, provided one additional counterterm is included compared to the 2-dimensional case [1] which can be interpreted as divergent shift of the field φ. The known results for the Kontsevich model allow to obtain the genus expansion of the free...
متن کاملHartley Series Direct Method for Variational Problems
The computational method based on using the operational matrix of anorthogonal function for solving variational problems is computeroriented. In this approach, a truncated Hartley series together withthe operational matrix of integration and integration of the crossproduct of two cas vectors are used for finding the solution ofvariational problems. Two illustrative...
متن کاملSADDLE POINT VARIATIONAL METHOD FOR DIRAC CONFINEMENT
A saddle point variational (SPV ) method was applied to the Dirac equation as an example of a fully relativistic equation with both negative and positive energy solutions. The effect of the negative energy states was mitigated by maximizing the energy with respect to a relevant parameter while at the same time minimizing it with respect to another parameter in the wave function. The Cornell pot...
متن کاملA Simple Method for the Preparation of Cis-(3-Azido-4-Styryl)-2-Azetidinone
The synthesis of the title compound is described. Deprotection of Cis(N-Trityl-3-azido-4-Styryl)-2-azetidinone to Cis-(3-azido-4-styryl)-2-azetidinone was found to be accelerated by the special salt effect under acidic condition
