Research Abstract

Entanglement entropy is one of the characteristic quantities in the topological quantum computation. The entanglement entropy, especially topological entanglement entropy, is intimately related to the quantum invariants of knots and 3-manifolds. We studied the colored Jones polynomials for knots and links. We exactly analyzed the colored Jones polynomial for torus knots, and we obtained explicit relationship with classical topological invariants such as torsions. We also studied the Fourier expansion of modular forms, and obtained a relationship between their asymptotic behavior and the entropy of complex manifolds.
