In this article, we first demonstrate a fixed point result under certain contraction in the setting of controlled b-Branciari metric type spaces.

Thereafter, we specifically consider a following boundary value problem (BVP) for a singular fractional differential equation of order α:
$$ \begin{aligned} &{}^{c}D^{\alpha }v(t) + h \bigl(t,v(t) \bigr) = 0,\quad 0< t< 1, \\ &v''(0) = v'''(0) = 0, \\ &v'(0) = v(1) = \beta \int _{0}^{1} v(s) \,ds, \end{aligned} $$where \(3<\alpha <4\), \(0<\beta <2\), \({}^{c}D^{\alpha }\) is the Caputo fractional derivative and h may be singular at \(v = 0\).
-
Eventually, we investigate the existence and uniqueness of solutions of the aforementioned boundary value problem of order α via a fixed point problem of an integral operator.

具有积分边界条件的奇异分数阶微分方程解的不动点法
在本文中,我们首先证明受控b -Branciari度量类型空间的设置在一定收缩下的不动点结果。
-
此后,我们具体考虑阶数为α的奇异分数阶微分方程的以下边值问题(BVP) :
$$ \ begin {aligned}&{} ^ {c} D ^ {\ alpha} v(t)+ h \ bigl(t,v(t)\ bigr)= 0,\ quad 0 <t <1,\ \&v''(0)= v'''(0)= 0,\\&v'(0)= v(1)= \ beta \ int _ {0} ^ {1} v(s)\,ds ,\ end {aligned} $$其中\(3 <\ alpha <4 \),\(0 <\ beta <2 \),\({} ^ {c} D ^ {\ alpha} \)是Caputo分数导数,并且h在\(v = 0 \)。
-
最后,我们通过积分算子的不动点问题,研究了上述α阶边值问题解的存在性和唯一性。
