摘要：There is only limited experimental evidence for the existence in nature of phase transitions of
Ehrenfest order greater than two. However, there is no physical reason for their non-existence,
and such transitions certainly exist in a number of theoretical models in statistical physics and
lattice field theory. Here, higher-order transitions are analysed through the medium of partition
function zeros. Results concerning the distributions of zeros are derived as are scaling relations
between some of the critical exponents.
