Conclusions and future work We have generalized to an arbitrary dimension a one-dimensional discrete probabilistic model which, for one dimension, yields q-gaussians in the thermodynamic limit. We have generalized to an arbitrary dimension a one-dimensional discrete probabilistic model which, for one dimension, yields q-gaussians in the thermodynamic limit. Our two-dimensional model, though containing one-dimensional conditional distributions yielding q-gaussians doesn’t seem to yield bidimensional q-gaussians as limiting probability distributions for.

The formulation of a probabilistic model yielding multidimensional q-gaussians in the thermmodynamic limit is still an open question.
