Recently, Majorana fermions became a hot topic in condensed matter physics. The concepts: vortex, domain wall, and kink often appear in these articles about Majorana fermions. I have no idea about the different characteristic of these concepts.
Please give a pedagogical introduction to these definitions and list the common and different characteristic of the vortex, domain wall, and kink in detail.
