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…
Batalin-Vilkovisky quantization of symmetric Chern-Simons theory
Won Tae Kim, Chang-Yeong Lee, Dong Won Lee
We study the manifestly covariant three-dimensional symmetric Chern-Simons action in terms of the Batalin-Vilkovisky quantization method. We find that the Lorentz covariant gauge f…
