To study the influence of bulk fermion or bulk gauge field I consider a five-dimensional four-fermion interaction model and a non-Abelian gauge field theory as simple models where the chiral symmetry is broken down dynamically. Using a four-dimensional Lagrangian induced from the five-dimensional theory, I calculate the dynamically generated fermion mass and show how the extra dimension affects the chiral phase transition in the RS background.4 pages, Talk presented at the 11th Russian Gravitational Conference (GRG11), Tomsk, 1-7 July 2002High Energy Physics - Phenomenologytext
