Symplectic Embedding of a Massive Vector-Tensor Theory with Topological Coupling
Yong-Wan Kim, Chang-Yeong Lee, Seung-Kook Kim +1
In the symplectic Lagrangian framework we newly embed an irreducible massive vector-tensor theory into a gauge invariant system, which has become reducible, by extending the config…
Theta functions on Noncommutative T^4
Hoil Kim, Chang-Yeong Lee
We construct the so-called theta vectors on noncommutative T^4, which correspond to the theta functions on commutative tori with complex structures. Following the method of Dieng a…
Deformed Hyperkähler Structure for K3 Surfaces
Chang-Yeong Lee
We apply the method of algebraic deformation to N-tuple of algebraic K3 surfaces. When N=3, we show that the deformed triplet of algebraic K3 surfaces exhibits a deformed hyperkähl…
N-Point Deformation of Algebraic K3 Surfaces
Hoil Kim, Chang-Yeong Lee
We consider N-point deformation of algebraic K3 surfaces. First, we construct two-point deformation of algebraic K3 surfaces by considering algebraic deformation of a pair of commu…
Noncommutative K3 Surfaces
Hoil Kim, Chang-Yeong Lee
We consider deformations of a toroidal orbifold and an orbifold of quartic in . In the case, we construct a family of noncommutative K3 surfaces obtained…
Noncommutative Torus from Fibonacci Chains via Foliation
Hyeong-Chai Jeong, Eunsang Kim, Chang-Yeong Lee
We classify the Fibonacci chains (F-chains) by their index sequences and construct an approximately finite dimensional (AF) -algebra on the space of F-chains as Connes did on…
