TY - JOUR AU - Budişan, Sorin PY - 2016/04/12 Y2 - 2024/03/29 TI - Generalizations of Krasnoselskiĭ's fixed point theorem in cones and applications JF - Topological Methods in Nonlinear Analysis JA - TMNA VL - 43 IS - 1 SE - DO - UR - https://apcz.umk.pl/TMNA/article/view/TMNA.2014.003 SP - 23 - 52 AB - We give some generalizations of Krasnosel'skiĭ's fixed point theorem in cones,replacing norms with functionals. We will apply these theorems to obtain atleast one positive solution for the boundary value problems for second-orderdifferential equations.Two positive solution results are also obtained. ER -
