 作者：Mohammed Al-Refai 来源：[J].Electronic Journal of Differential Equations(IF 0.426), 2012, Vol.2012 (191,), pp.1-12DOAJ 摘要：In this article, we discuss the basic theory of boundary-value problems of fractional order $1 < delta < 2$ involving the Caputo derivative. By applying the maximum principle, we obtain necessary conditions for the existence of eigenfunctions, and show analytical lower and upper ...
