Abstract In this paper, we construct the associated vertex operator algebras for all N $$ \mathcal{N} $$ = 2 superconformal field theories of rank one. We give a uniform presentation through free-field realizations, which turns out to be a particular

Abstract We present free field realizations for the associated vertex operator algebras of a number of four-dimensional N $$ \mathcal{N} $$ = 2 superconformal field theories. Our constructions utilize an exceptionally small set of chiral bosons whose

We make a preliminary investigation into twisted $A_{2n}$ theories of class S. Contrary to a common piece of folklore, we establish that theories of this type realise a variety of models of Argyres-Douglas type while utilising only regular punctur

Abstract Every four-dimensional N=2 $$ \mathcal{N}=2 $$ superconformal field theory comes equipped with an intricate algebraic invariant, the associated vertex operator algebra. The relationships between this invariant and more conventional protected

American politics is in a state of crisis but it is not clear why. Nor do we know what to do about it. Reinhold Niebuhr helps us understand what is wrong with our politics and research into the workings of the brain confirms his analysis. Call it sin

In the TQFT formalism of Moore–Tachikawa for describing Higgs branches of theories of class $${\mathcal {S}}$$ S , the space associated to the unpunctured sphere in type $${{\mathfrak {g}}}$$ g is the universal centraliser $${\mathfrak {Z}}_G$$ Z G

The correspondence between four-dimensional $\mathcal{N}=2$ superconformal field theories and vertex operator algebras, when applied to theories of class $\mathcal{S}$, leads to a rich family of VOAs that have been given the monicker chiral algebras

The authors study in detail an algebraic structure (vertex operator algebra VOA) that exists in $N=2$ superconformal field theories in four dimensions. Focusing on a particular class of these theories and employing the method of free-field realizatio
