摘要：We investigate a singular fractional differential equation with an infinite-point fractional boundary condition, where the nonlinearity f ( t , x ) $f(t,x)$ may be singular at x = 0 $x = 0$ , and g ( t ) $g(t)$ may also have singularities at t = 0 $t= 0$ or t = 1 $t=1$ . We establish the existence of positive solutions using the fixed point index theory in cones.
