The author considers an impulsive boundary value problem involving the one-dimensionalp-Laplacian-(φp (u′))′=λωtft,u,  0<t<1,  t≠tk,  Δu|t=tk=μIktk,  utk,  Δu′|t=tk=0,  k=1,2,…,n,  au(0)-bu′(0)=∫01‍g(t)u(t)dt,u′(1)=0, whereλ>0andμ>0are two parameters. Using fixed point theories, several new and more general existence and multiplicity results are derived in terms of different values ofλ>0andμ>0. The exact upper and lower bounds for these positive solutions are also given. Moreover, the approach to deal with the impulsive term is different from earlier approaches. In this paper, our results cover equations without impulsive effects and are compared with some recent results by Ding and Wang.

We consider the following boundary value problemwhere λ > 0 and 1 ≤ p ≤ n – 1 is fixed. The values of λ are characterized so that the boundary value problem has a positive solution. Further, for the case λ = 1 we offer criteria for the existence of two positive solutions of the boundary value problem. Upper and lower bounds for these positive solutions are also established for special cases. Several examples are included to dwell upon the importance of the results obtained.

The existence and multiplicity of positive solutions for the nonlinear fractional differential equation boundary value problem (BVP) DC0+αyx+fx,yx=0,   0<x<1, y0=y′1=y″0=0 is established, where 2<α≤3,  CD0+α is the Caputo fractional derivative, and f:0,1×0,∞⟶0,∞ is a continuous function. The conclusion relies on the fixed-point index theory and the Leray-Schauder degree theory. The growth conditions of the nonlinearity with respect to the first eigenvalue of the related linear operator is given to guarantee the existence and multiplicity.
