SUMMARY
The null space of the operator TΦ, defined as TΦ: V → R where V is the space of continuously differentiable functions ƒ over the interval [0,1] and Φ = x, consists of all functions ƒ such that ∫ƒ'(x)x dx = 0. By applying integration by parts, it is established that the null space includes functions that satisfy the condition ƒ(0) = 0, leading to the conclusion that the null space is spanned by functions that are constant on the interval [0,1]. This analysis is crucial for understanding the behavior of linear operators in functional spaces.
