- W2131865935 abstract "Theobservationalevidenceforthe accelerated expansion rateoftheuniverse,and theintroduction oftheconcept ofDark Energy hasputtheoreticalcosm ology into crisis. Thisisdue to the factthatdespite an increasing am ount and quality ofdata,no m odelhasbeen proposed thusfarthatisable to give a com pletely satisfactory theoretical explanation oftheseobservations. Am ong them any dierentwaysto achievecosm icacceleration,them odication ofgravity and in particularhigher ordergravity hasrecently gained m uch attention (1{5). The reason forthispopularity isdue to the factthatthese m odels provide a som ewhat m ore naturalexplanation ofthe cosm ic acceleration: this eect is due to corrections to Einstein gravity which are directly related to the characteristic propertiesofthe gravitationalinteraction. M ost investigationsofhigherordergravityhavefocused on Fourth OrderGravity(FOG),i.e.,on gravitationalLagrangian's in which thecorrectionsareatm ostoforderfourin them etricand in whatfollowswewillalsofocuson thesem odels. Becausetheeld equationsresulting from FOG areextrem ely com plicated,dicultconceptualand technicalissues arisewhich need to beresolved in orderto uncoverthedetailed physicsofthesem odels.Consequently itisim portant to develop new m ethodswhich are able to assistin resolving these problem s.
