Strong similarities have been long observed between the Galois (Categories Galoisiennes) and the Tannaka (Categories Tannakiennes) theories of representation of groups. In this paper we construct an explicit (neutral) ...

We classify the class S theories of type E-7. These are four-dimensional N = 2 superconformal field theories arising from the compactification of the E-7 (2, 0) theory on a punctured Riemann surface, C. The classification ...

Considering unbalanced and non linear three-phase three-wire power systems, this paper discusses the relationship and discrepancies among three modern power theories. The considered approaches were the so called FBD Theory ...

The existence of an interpolating master action does not guarantee the same spectrum for the interpolated dual theories. In the specific case of a generalized self-dual (GSD) model defined as the addition of the Maxwell ...
