The Grone-Merris Conjecture
Hua Bai
In spectral graph theory, Grone and Merris conjecture that the spectrum of the Laplacian matrix of a finite graph is majorized by the conjugate degree sequence of this graph. We gi…
Local representations of the quantum Teichmuller space
Hua Bai, Francis Bonahon, Xiaobo Liu
We introduce a certain type of representations for the quantum Teichmuller space of a punctured surface, which we call local representations. We show that, up to finitely many choi…
Quantum Teichmüller spaces and Kashaev's 6j-symbols
Hua Bai
The Kashaev invariants of 3-manifolds are based on -symbols from the representation theory of the Weyl algebra, a Hopf algebra corresponding to the Borel subalgebra of $U_q(sl(…
Intersecting non-SUSY -brane with chargeless 0-brane as black -brane
Hua Bai, J. X. LU, Shibaji Roy
Unlike BPS -brane, non-supersymmetric (non-susy) -brane could be either charged or chargeless. As envisaged in [hep-th/0503007], we construct an intersecting non-susy -bra…
A Uniqueness Property for the Quantization of Teichmüller Spaces
Hua Bai
Chekhov, Fock and Kashaev introduced a quantization of the Teichmüller space of a punctured surface , and an exponential version of this construction was deve…
Tachyon condensation on the intersecting brane-antibrane system
H. Bai, J. X. Lu, S. Roy
We generalize our study of the tachyon condensation on the brane-antibrane system [hep-th/0403147] to the intersecting brane-antibrane system. The supergravity solutions of the int…
