This thesis deals with frustration effects in spin models. An analytical study of critical phenomena in three-dimensional hyperbolic space is undertaken and a new critical fixed point is shown to exist. Moreover, the so-called "windmill spin model" is studied using various Monte Carlo algorithms and analytical calculations
