– M oser ▁theorem ▁to ▁the ▁problem . ▁The ▁original ▁work ▁of ▁Vladimir ▁Arnold ▁on ▁this ▁theorem ▁attempted ▁to ▁use ▁it ▁to ▁show ▁the ▁stability ▁of ▁the ▁solar ▁system ▁or ▁similar ▁systems ▁of ▁planet ary ▁or bits , ▁but ▁this ▁worked ▁only ▁for ▁the ▁three - body ▁problem ▁because ▁of ▁a ▁deg ener acy ▁in ▁Arnold ' s ▁mathematical ▁framework . ▁Pin z ari ▁showed ▁how ▁to ▁eliminate ▁this ▁problem , ▁and ▁extended ▁the ▁solution ▁to ▁larger ▁numbers ▁of ▁bodies , ▁by ▁developing ▁" a ▁rotation - in variant ▁version ▁of ▁the ▁K AM ▁theory ". ▁ ▁Education ▁and ▁career ▁Pin z ari ▁earned ▁master ' s ▁degrees ▁in ▁both ▁physics ▁and ▁mathematics ▁from ▁S ap ienza ▁University ▁of ▁Rome , ▁in ▁ 1 9 9 0 ▁and ▁ 1 9 9 6 ▁respectively . ▁She ▁completed ▁her ▁doctor ate ▁in ▁ 2 0 0 9 ▁at ▁Roma ▁Tre ▁University ▁under ▁the ▁super vision ▁of ▁Luigi ▁Ch ier chia . ▁She ▁joined ▁the ▁fac ulty ▁of ▁the ▁University ▁of ▁Nap les ▁Feder ico ▁II ▁since ▁ 2 0 1 3 , ▁and ▁later ▁moved ▁to ▁the ▁University ▁of ▁Pad ova . ▁ ▁Rec ogn ition ▁She ▁was ▁an ▁Inv ited ▁Spe aker ▁at ▁the ▁ 2 0 1 4 ▁International ▁Congress ▁of ▁Mathemat icians , ▁in ▁Se oul , ▁speaking ▁on ▁her ▁work ▁in ▁the ▁session ▁on ▁dynam ical ▁systems ▁and ▁ordinary ▁differential ▁equations . ▁ ▁References ▁ ▁Category : Year ▁of ▁birth ▁missing ▁( l iving ▁people ) ▁Category : L iving
