具有共振的边值问题解的存在性
The Existence of Solutions for Boundary Value Problem at Resonance
【摘要】 利用Mawhin的重合度理论,研究具有共振的n-阶m-点边值问题x(n)(t)=f(t,x(t),x′(t),…,x(n-1)(t)),t∈(0,1)x(0)=x(η),x′(0)=x″(0)=…=x(n-2)(0)=0,x(n-1)(1)=αix(n-1)(ξi)解的存在性,其中n≥2,m≥3,f:[0,1]×Rn→R将有界集映为有界集,且当x(t)∈Cn-1[0,1]时,f(t,x(t),x′(t),…,x(n-1)(t))∈L1[0,1],0<ξ1<ξ2<…<ξm-2<1,0<η<1,αi∈R.在这里并不要求f具有连续性.
【Abstract】 Using the coincidence degree theory due to Mawhin,we study the existence ofsolutions for n-order m-point boundary value problemwhere n≥2,m≥3,f:[0,1]×Rn→R mapping bounded set to bounded set,f(t,x(t),x’(t),…,x(n-1)(t))∈L1[0,1]forx(t)∈Cn-1[0,1],0<ξ1<ξ2<…<ξm-2<1,0<η<1,αi∈R.We don’t need that f is continuous.
