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 ...

Unlike business models of private banks based on profit maximization and shareholder-oriented governance, alternative banks (such as cooperative banks, government savings banks, and special purpose banks) share business ...

We study a class of lattice field theories in two dimensions that includes gauge theories. We show that in these theories it is possible to implement a broader notion of local symmetry, based on semisimple Hopf algebras. ...

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 ...

Publications on fuzzy set theory and its applications have grown exponentially. The increasing rate of developments in the field is a response to diverse factors, including the need for robust mathematical approaches ...
