D-dimensional integrals

Mathematical appendices introduce (5-functious, Fourier transform, or d-dimensional integration over Gaussian functions, respectively. 

In order to calculate the d-dimensional integral (Equation 42) must be evaluated. For d > 2, this integral formally diverges, unless a cut-off is accepted in Equation 5.1- 62. 

The integration in (5.2.12) is carried out over the surface of a d-dimensional unit radius sphere.

Using the integral theorem, a volume integral V ro) in (5.1.26) for d-dimensional sphere of the radius ro is transformed into a surface one, from where one gets... 

In equilibrium NVE Molecular Dynamics simulation new molecular positions are obtained solving by Newton s equation of motion numerically. To solve Equation Al we use Equation A3 and also specify the initial and boundary conditions of our d dimensional system. This results in a set of d x TV coupled second-order ordinary differential equations and a total of d x TV degrees of freedom. This set of equations are discretized and new positions and velocities for each atom is found numerically by integrating forward in time. Below we give the MD recipe ... 

Many problems in D-dimensional statistical mechanics with nearest-neighbor interactions can be converted into quantum mechanics problems in (D — 1) dimensions of space and one dimension of time [84]. The quantum theory arises here in a Feynman path integral formulation [85].

The integral on the right-hand side is a number which can be easily calculated. In fact, let us recall that the area Q(d) of the surface of a ball of unit radius in a d-dimensional space is given by (F.l)... 

The effect of the exponential factor is to make the volume of the ion inaccessible to solvent molecules, i.e., to exclude a sphere of radius d centred on the ion from all h three-dimensional integrations, initially extended to the whole volume V. This results from the fact that the interactions are functions of relative distances measured from the centres of the particles involved. The effect of volume exclusion, can be dealt with in a systematic way by introducing the Mayer functions... 

First, we briefly review statistical foundations of the Monte Carlo (MC) integration. The heart of the MC integration is the central limit theorem, which states the characterization for the average of random samples. Suppose d-dimensional space, the corresponding position vector X = (xi, X2,..., Xd), and a set of mutually independent M position vectors X, / = 1,2,..., M which are distributed according to the probability density P(X). The probability density P(X) should satisfy the following relations.
