Abstract: Let be a compact Hausdorff space and let denote the subsets of which are either open or closed. A quasi-linear functional is a map which is linear on singly generated subalgebras and such that for some . There is a one-to-one correspondence between the quasi-linear functional on and the set functions such that i) , ii) If with and disjoint, then , iii) There is an such that whenever are disjoint open sets, , and iv) if is open and , there is a compact such that whenever is open, then . The space of quasi-linear functionals is investigated and quasi-linear maps between two spaces are studied.
