Abstract
In this paper, we discuss a nonlinear fractional order boundary value problem with nonlocal Erdélyi–Kober and generalized Riemann–Liouville type integral boundary conditions. By using Mawhin continuation theorem, we investigate the existence of solutions of this boundary value problem at resonance. It is shown that the boundary value problem \t\t\tDqcx(t)=f(t,x(t),x′(t)),t∈[0,T],1<q≤2,x(0)=αIηγ,δx(ζ),x(T)=βρIpx(ξ),\\documentclass[12pt]{minimal}\t\t\t\t\\usepackage{amsmath}\t\t\t\t\\usepackage{wasysym}\t\t\t\t\\usepackage{amsfonts}\t\t\t\t\\usepackage{amssymb}\t\t\t\t\\usepackage{amsbsy}\t\t\t\t\\usepackage{mathrsfs}\t\t\t\t\\usepackage{upgreek}\t\t\t\t\\setlength{\\oddsidemargin}{-69pt}\t\t\t\t\\begin{document}$$\\begin{gathered} {}^{c}D^{q}x(t)=f \\bigl(t, x(t),x'(t) \\bigr),\\quad t \\in[0,T], 1< q\\leq2, \\\\ x(0)=\\alpha I^{\\gamma,\\delta}_{\\eta}x(\\zeta),\\qquad x(T)=\\beta{}^{\\rho }I^{p}x( \\xi),\\end{gathered} $$\\end{document} has at least one solution under some suitable conditions, where alpha, betainmathbb{R}, 0<zeta, xi<T.

In this paper, we intend to discuss the following boundary value problem at resonance: cDqx(t) = f (t, x(t), x (t)), t ∈ [0, T], x(0) = αIηγ,δx(ζ ), x(T) = βρIpx(ξ ), 0 < ζ, η ≤ T, (1)where cDq is the Caputo fractional derivative of order 1 < q ≤ 2, Iηγ,δ is a Erdélyi–Kober type integral of order δ > 0 with η > 0 and γ ∈ R, ρIp denotes the generalized Riemann– Liouville type integral of order p > 0, ρ > 0, and α, β ∈ R.Boundary value problems at resonance have aroused people’s interest these days
