The region occupied by the Hungaria asteroids has a high dynamicalcomplexity. In this paper, we analyse the main dynamic structures and theirinfluence on the known asteroids through the construction of maps of initialconditions. We evolve a set of test particles placed on a perfectly rectangulargrid of initial conditions during 3 Myr under the gravitational influence ofthe Sun and eight planets, from Mercury to Neptune. Moreover, we use the methodMEGNO in order to obtain a complete dynamical portrait of the region. Acomparison of our maps with the distribution of real objects allows us todetect the main dynamical mechanisms acting in the domain under study such asmean-motion and secular resonances. Our main results is the existence of asmall area inside a stable region where are placed the Hungaria asteroids. Wefound that the influence of Mars has an important role for the dynamicstructure of the region, defining the limits for this population of asteroids.Our result is in agreement with previous studies, which have indicated theimportance of the eccentricity of Mars for the stability of Hungaria asteroids.However, we found that the secular resonance resulting from the precession ofperihelion due to a coupling with that of Jupiter proposed as limit for theHungaria region could not be determinant for this population of asteroids.
