    "abstract": "The Nowak modification of the Sznajd opinion dynamics model on the square\nlattice assumes that with probabilities beta and gamma the opinions flip due to\nmass-media advertising from down to up, and vice versa. Besides, with\nprobability alpha the Sznajd rule applies that a neighbour pair agreeing in its\ntwo opinions convinces all its six neighbours of that opinion. Our Monte Carlo\nsimulations and mean-field theory find sharp phase transitions in the parameter\nspace.",
