摘要
本文在f(t,x),fx(t,x),β(t)连续,fx(t,x)≥-β(t),β(t)≤π20+α24,β(t)π20+α24,π0为方程αsinx2+xcosx2=0的最小正根条件下,证明了第二边值问题.x"=αx+f(t,x),x(0)=a,x(1)=b对于任给实数α,a。
In this paper, we study a class of pseudoulinear second boundary value problem of x'=αx+f(t,x),x(0)=a,x(1)=b.We proved existence and uniqueness for the solution under the conditions that f(t,x),f x(t,x),β(t)are all continuous and f x(t,x)≥-β(t),β(t)≤π 2 0+α 24,β(t)π 2 0+α 24,where π 0 is the minimal positive root of the αsinx2+xcosx2=0.
