On electronic and transport "anomalies" in layered oxides

We briefly discuss some electronic and transport "anomalies" observed in superconducting perovskites. In particular we consider: (i) the complex electronic (and crystallographic) phase diagram, (ii) the symmetry of the gap with a special emphasis on the evidence for s-wave component in various experiments, and (iii) non-Fermi-liquid transport in superconducting Sr2RuO4-delta perovskite (T-c < 1 K) that, like LSCO cuprate, exhibits linear resistivity up to 1050 K.
