| Abstract: | A complete analysis of dynamical scale symmetry breaking in 2+1-dimensional QED at both zero and finite temperature is presented
by looking at solutions to the Schwinger-Dyson equation. In different kinetic energy regimes we use various numerical and
analytic techniques (including an expansion in large flavour number). It is confirmed that, contrary to the case of 3+1 dimensions,
there is no dynamical scale symmetry breaking at zero temperature, despite the fact that chiral symmetry breaking can occur
dynamically. At finite temperature, such breaking of scale symmetry may take place.
