Three problems are studied. (i) The optimal shape of the electronic densities of states of metal and gapped insulator related by a geometrical distortion, for a temperature induced transition between them. (ii) The dependence of valence band width on cation identity and the temperature of the metal Mott‐Hubbard insulator transition in the series RENiO 3 (RE = Rare Earth). (iii) Electronic insights into the loss of a Jahn‐Teller distortion at Mn during the insulator‐metal transition in La 1−x Sr x MnO 3 as x increases but not at Cu for La 2−x Sr x CuO 4 .
