From the text: In this paper, we prove two conjectures of H. Dobbertin et al. [Discrete Math. 267, No. 1–3, 95–112 (2003; Zbl 1028.11076)] in characteristic 3. We also give a new family of APN power mappings in characteristic 5. In the last section, we make some remarks about theorems of Z.-B. Zha and X.-L. Wang [Sci. China, Math. 53, No. 8, 1931–1940 (2010; Zbl 1246.12007)].For the entire collection see [Zbl 1248.11004].
