Abstract: The incomplete Gamma function $\gamma(\ab,x)$ and its associated functions $\gamma(\ab,x _+)$ and $\gamma(\ab,x _-)$ are defined as locally summable functions on the real line and some convolutions and neutrix convolutions of these functions and the functions $x^r$ and $x_-^r$ are then found.

Keywords: Gamma function, incomplete Gamma function, convolution, neutrix convolution
