# Integral in an infinte dimensional space

let,s suppose we have to perform an integral into a infinite dimensional space,then we would use the Montecarlo,s Method as it is known to be independent of the dimension of the integral, but my problem is still the same..¿how do you define a point into a infinite dimensional space?...how would you perform this integral?..

This is useful in Quantum Field Theory where such integrals appear.

Hi,
In this case you should know what is the property of this space,then construct a knew measure of integration like Feynmann path integral in quantum mechanics
