Simple Structures with Complex Symmetry
We define the automorphism spectrum of a computable structure M, a measurement of the complexity of the symmetries of M, and prove that certain sets of Turing degrees can be realized as automorphism spectra, while certain others cannot.
متن کاملSimple Vector Fields with Complex Behavior
We present a technique for constructing simple vector fields with complex behaviour and illustrate this technique with two examples. The examples we construct, besides describing partial behaviour of complicated systems, have an interest of their own as they illustrate complicated behaviour in a tractable way.
متن کاملThe Effect of Textual Enhancement Types on EFL Learners’ Grammatical Awareness of Simple and Complex Structures
The purpose of this study was to investigate the effect of textual enhancement types on English as Foreign Language ( EFL ) learn er s ’ grammatical awareness of simple and complex structures. A nu m- ber of 104 learners from Ayandegan Institute, in Tehran, participated in this study. To homogenize the samples, the researchers administered a placement Michigan Test of English language to the p...
متن کاملComplex magnetic fields in an active region
High-resolution observations of the full Stokes vector in Fe i spectral lines around 5250 Å obtained at the Swedish Vacuum Solar Telescope on La Palma with the ZIMPOL I Stokes polarimeter in a complex active region reveal the presence of anomalously shaped Stokes profiles indicating the coexistence of at least two magnetic components within the same spatial resolution element. These Stokes prof...
متن کاملDynamical Emergence of Complex Structures in Field Theories
Nonlinear field theories can be used to study both standard physics questions, or to study questions such as the emergence of order and complexity. These theories are generally derived from the symmetries of a given problem and the interactions that respect those symmetries. Formally one can then quantize the system to find the masses of the fundamental excitations, but this procedure generally...
