Kniga posvyashchena issledovaniyu nelineynykh rezhimov evolyutsii v dinamicheskikh modelyakh galaktik i ikh podsistem, a takzhe zadacham vosstanovleniya nestatsionarnogo potentsiala po zadannomu semeystvu evolyutsioniruyushchikh vo vremeni ploskikh orbit v nekotorykh nestatsionarnykh zadach mekhaniki. V rabote proveden nelineynyy analiz kolebaniy besstolknovitel'nogo nevrashchayushchegosya sferoida, vypolneno issledovanie nelineynoy model'noy zadachi, rassmatrivayushchey diskretnuyu podsistemu vzaimnoprityagivayushchikhsya zvezd pervogo pokoleniya vnutri nevozmushchennoy svobodno szhimayushcheysya gazovoy protogalaktiki. Krome togo, predlozhena dostatochno interesnaya analiticheskaya model' gravitiruyushchego shara, sostoyashchego iz raspredelennogo veshchestva i diskretnoy podsistemy massivnykh kvazitochechnykh tel, privedeny nestatsionarnye analogi uravneniya Sebekheya dlya obratnykh zadach mekhaniki, dany ikh prilozheniya v vide model'nykh zadach dlya dinamiki gravitiruyushchikh sistem. Dannaya kniga rekomenduetsya, v pervuyu ochered', nauchnym sotrudnikam, molodym uchenym i PhD studentam, spetsializiruyushchimsya v oblasti zvezdnoy dinamiki, nebesnoy mekhaniki, a takzhe magistrantam i bakalavram fizicheskikh i matematicheskikh fakul'tetov.
