✦ Synopsis

The critical behaviour of an exactly solvable model with developed classical and quantum fluctuations depending on the temperature, the quantum parameter and the space dimension, is studied. The critical exponents on the whole phase diagram, including two multicritical points (quantum and classical), are calculated.
