* Abstract:

According to a rigorous theorem by Hohenberg, Mermin and Wagner, long range order in such systems does not exist in two dimensions. However, this does not forbid the existence of superfluids and crystals in two dimensions. This talk will discuss theoretical and experimental studies of this class of two dimensional systems. Particular attention will be paid to some exact theoretical predictions and their experimental verification.
