Language Transformations During Contact Interaction

Complex Contact and Lift Transformations

We study mappings from sets of real variables into complex variables, which extend features of lift and contact transformations between real variables that we explored in a previous paper. In particular the relationship between lifts in R and the CauchyRiemann equations for functions of n complex variables is discussed. Explicit examples are given to illustrate the anatomy of such transformatio...

Language Change and Language Contact

Language Contact: Peaceful Coexistence or Emergence of a Contact Language

This paper presents a simple model of linguistic priming between languages in contact, based on the utterance selection model (USM) for language change of Baxter et al. (2006). It will be shown that the emergence or the non-emergence of a new contact language depends on the way potentially bilingual agents choose a language to communicate.

Comparison of Union-Preserving and Contact Transformations.

a given group then it is not possible for one of them to be contained in the other. If the operators which are commutative with one of the non-invariant operators of one of the groups under consideration do not always constitute an Abelian group then the prime number of the conjugates for each of its sets of conjugate operators of its non-invariant operators must be the same and hence these gro...
