But in quantum ﬁeldtheorytherecanbeaninﬁnitenumberofvariables,andsoweneedtoinvestigatehowtheGaussianintegrals behave when the variable xbecomes the n-dimensional vector x, where the dimension nmay be inﬁnite. For some of them analytical solution is presented and for some others, the solution is written in terms of the Owen’s T-function (Owen, 1980). /Filter /LZWDecode ©2005 BE Shapiro Page 3 This document may not be reproduced, posted or published without permission.

Indefinite integral. Lines such as those shown below would likely give much better approximations in most cases. Such a rule would have x 1 = a and x n = b, and it turns out that the appropriate choice of the n−2 interior nodes should be the (transformed) roots of P0 n−1 (x) in (−1,1).

Remark: Gaussian quadrature formula (more in Table 4.12) () 1 −1 ≈ () =1. Solutions to Gaussian Integrals Douglas H. Laurence Department of Physical Sciences, Broward College, Davie, FL 33314 The basic Gaussian integral is: I= Z 1 1 e 2 x dx Someone gured out a very clever trick to computing these integrals, and \higher-order" integrals of xne x2. This criterion is illustrated for the Gaussian integral R e x2dx from prob-ability theory, the logarithmic integral R dt=log(t) from the study of primes, and elliptic integrals.

N.B. 1 When we repeat an experiment numerous times and average our results, the random variable representing the average or mean tends to have a normal distribution as the number of experiments becomes large. Matrix integrals are used for calculations in several different areas of physics and mathematics; for example quantum field theory, string theory,quantumchromodynamics,andrandommatrixtheory.
