Resumen de Moderation of sigma-finite Borel measures

J. Novoa Fernández

• We establish that a $\sigma$-finite Borel measure $\mu$ in a Hausdorff topological space $X$ such that each open subset of $X$ is $\mu$-Radon, is moderated when $X$ is weakly metacompact or paralindelöf and also when $X$ is metalindelöf and has a $\mu$-concassage of separable subsets. Moreover, we give a new proof of a theorem of Pfeffer and Thomson [5] about gage measurability and we deduce other new results.
