Abstract: We applied Frequency Map Analysis FMA - a method that is widely used toexplore dynamics of Hamiltonian systems - to beam-beam effects study. Themethod turned out to be rather informative and illustrative in the case of anovel Crab Waist collision approach, when -crab- focusing of colliding beamsresults in significant suppression of betatron coupling resonances. Applicationof FMA provides visible information about all working resonances, their widthsand locations in the planes of betatron tunes and betatron amplitudes, so theprocess of resonances suppression due to the beams crabbing is clearly seen.
