	Fixed Point Theory, Volume 26, No. 2, 2025, 651-662, May 1st, 2025 DOI: 10.24193/fpt-ro.2025.2.19 Authors: Qingcong Song and Xinan Hao Abstract: This paper is devoted to studying convolution equations with nonlocal boundary condition. By means of the theory of fixed point index, some existence, multiplicity, and nonexistence results for positive solutions are derived in terms of different values of parameter λ. Key Words and Phrases: Convolution equation, nonlocal boundary condition, positive solution, fixed point index, multiplicity. 2010 Mathematics Subject Classification: 34B10, 34B18.
