state ρ defined in Eq.(2.3) with g = ( q$_{1}$, q$_{2}$, q$_{3}$ ) reduces to

The eigenvalues and eigenvectors of ρ are summarized at Table I.

At Table I M$_{1}$ , M$_{2}$ , Λ$_{±}$ and Δ$_{±}$ are given by

Then, the deformation of T can be obtained from the positivity condition of ρ . Since deformation should be a set of the boundary states, the condition of the deformation becomes

One can make two surfaces by making use of Eq.(3.3). Each surface corresponds to min( µ$_{−}$, ν$_{−}$ ) = µ$_{−}$ = 0 or min( µ$_{−}$, ν$_{−}$ ) = ν$_{−}$ = 0. Gluing these surfaces together yields the deformation of T . 

In Fig. 3 we plot the deformation of T when r = s = 0 . 3 (Fig. 3a), r = − s = 0 . 3 (Fig. 3b), r = s = 0 . 5 (Fig. 3c) and r = − s = 0 . 5 (Fig. 3d). For comparison we plot T together.
