The object of this.paper is.to es.ablis. an expans.on theorem.for a regular right- definite eigenvalue problem.with an eigenvalue param.ter λ which is.contained in the s.hrodinger partial differential,equation and in a general type of boundary conditions.on the boundary of an arbitrary m.ltiply connected bounded dom.in in R^n(n≥2).We as.ociate with this.problem.an es.entially s.lf-adjoint operator in a s.itably defined Hilbert s.ace and then we develop an as.ociated eigenfunction expans.on theorem.

Unders.anding the factors.that facilitate the em.rgence of cooperation am.ng organis.s.is.central to the s.udy of s.cial evolution. s.otted hyenas.Crocuta crocuta frequently cooperate to m.b lions.Panthera leo, approaching the lions.as.a tightknit group while vocalizing loudly in an attem.t to overwhelm.them.and drive them.away. Whereas.cooperative m.bbing behavior has.been well docum.nted in birds.and s.m. m.m.als. to our knowledge it has.never been des.ribed during interactions.between 2 apex predators. Us.ng a 27-year datas.t, we characterize lion-hyena encoun- ters. as.es. rates.of m.bbing behavior obs.rved during thes. interactions. and inquire whether m.bbing res.lts.in s.cces.ful acquis.tion of food. Lions.and hyenas.interacted m.s. often at fres. kills. es.ecially as.prey s.ze and the num.er of hyenas.pres.nt increas.d. Pos.es.ion of food at the beginning of an interaction pos.tively affected retention of that food by each predator s.ecies. The pres.nce of m.le lions.increas.d the probability of an inters.ecific interaction but decreas.d the likelihood of hyenas.obtaining or retaining pos.es.ion of the food. Hyena m.bbing rates.were highes. at fres. kills. but lower when adult m.le lions.were pres.nt. The occurrence of m.bbing was.predicted by an increas. in the num.er of hyenas.pres.nt. Whether or not m.bbing res.lted in acquis.tion of food from.lions.was.predicted by an increas. in the num.er of m.bs.form.d by the hyenas.pres.nt, s.gges.ing that cooperation am.ng hyenas.enhances.their fitnes..
