An Application of Analytic Methods to Smectic A Liquid Crystals, Dislocation and Crack

In this book, we emphasize the background of liquid crystals on discussion of soft-matter quasicrystals, i.e. matrix of soft-matter quasicrystals concerned here is liquid crystals, or more explicitly speaking, that the soft-matter quasicrystals are the quasicrystals in liquid crystals. However, it is not directly given a concrete liquid crystal example in the previous presentation. In the end of the book we give an example to discuss smectic A liquid crystal and its screw dislocation and crack, these are interesting topics, although they are not quasicrystal problem.
