Abstract. We discuss the Bose-Einstein condensation (BEC) for an ideal gas
of bosons in the framework of Tsallis's nonextensive
statistical mechanics.
We study the corrections to the standard BEC formulas
due to a weak nonextensivity of the system.
In particular, we consider three cases
in the D-dimensional space:
the homogeneous gas, the gas in a harmonic trap and
the relativistic homogenous gas.
The results show that small deviations from
the extensive Bose statistics produce remarkably large
changes in the BEC transition temperature.
