Mckay Correspondence
1 Introduction Conjecture 1.1 (since 1992) G ⊂ SL(n, C) is a finite subgroup. Assume that the quotient X = C n /G has a crepant resolution f : Y → X (this just means that K Y = 0, so that Y is a " noncompact Calabi–Yau manifold "). Then there exist " natural " bijections {irreducible representations of G} → basis of H * (Y, Z) (1) {conjugacy classes of G} → basis of H * (Y, Z) (2) As a slogan "...
متن کاملMcKay correspondence over non algebraically closed fields
The classical McKay correspondence for finite subgroups G of SL(2,C) gives a bijection between isomorphism classes of nontrivial irreducible representations of G and irreducible components of the exceptional divisor in the minimal resolution of the quotient singularity A2C/G. Over non algebraically closed fields K there may exist representations irreducible over K which split over K. The same i...
متن کاملColour valued scattering matrices from non simply-laced Lie algebras
A new set of exact scattering matrices in 1+1 dimensions is proposed by solving the bootstrap equations. Extending earlier constructions of colour valued scattering matrices this new set has its colour structure associated to non simply-laced Lie algebras. This in particular leads to a coupling of different affine Toda models whose fusing structure has to be matched in a suitable manner. The de...
متن کاملAn approach to non simply laced cluster algebras
We study cluster algebras associated to a quiver equipped with a group of admissible automorphisms. This enables us to realize cluster algebras of non simply laced types as quotients of cluster algebras of simply laced types. We then generalize well known results on cluster algebras as denominators theorems and, under some conditions, the linear independence of cluster monomials over Z.
متن کاملNon-simply-laced Clusters of Finite Type via Frobenius Morphism
By showing the compatibility of folding almost positive roots and folding cluster categories, we prove that there is a one-to-one correspondence between seeds and tilting seeds in non-simply-laced finite cases.
