    • The correlation functions (formula presented) in the Bragg glass and in the amorphous vortex glass are, different (Ref. at (formula presented) Therefore, these vortex solid phases cannot be, transformed into each other, and a termination of the phase transition line separating these phases cannot occur below the melting line. This phase transition line can terminate only on another phase transition line (i.e., on the melting curve)
    • The correlation functions (formula presented) in the Bragg glass and in the amorphous vortex glass are qualitatively different (Ref. 23) at (formula presented) Therefore, these vortex solid phases cannot be continuously transformed into each other, and a termination of the phase transition line separating these phases cannot occur below the melting line. This phase transition line can terminate only on another phase transition line (i.e., on the melting curve).

    • The upper region of single-vortex pinning was discussed by Larkin and Ovchinnikov (Ref. in the context of the origin of the peak effect in low-(formula presented) superconductors. Without account of thermal fluctuations, this region exists at magnetic fields near (formula presented) [when (formula presented)]. This follows from Eq. (8), which gives (formula presented) at (formula presented) Note that we show the boundary of this region only in Fig. 55

    • Note that the depinning line presented in Fig. 44 has a descending (with (formula presented)) branch which is not shown in Fig. 18 of Ref.,. This branch is due to the factor (formula presented) in Eq. (17), which was neglected in Eq. (4.88) of Ref. Of course, the part of the depinning line lying above the melting curve has only formal meaning, since we did not take into account that the shear modulus (formula presented) vanishes at the melting.)
