The application of pictures to decision problems and relative presentations
Regard the presentation P =< x; r > as a 2-complex. Then we have the second homotopy module 2(P). The elements of 2(P) can be represented by spherical pictures. This is the key idea for this thesis. We give this preliminary background in Chapter 1. In Chapter 2, we study properties of groups c...
