Abstract

Classical solutions for the open relativistic string with a single junction are examined and a new class of kinked solutions presented. An interpretation of the phenomena of reverse parametrisation on one arm is offered in terms of oriented chains and the consequence that this has for folded world sheets is discussed. A physical interpretation for certain junction sites is presented through interaction of the string with an external field.
