Rational Functions of a Complex Variable and Related Potential Curves.
This implies that in this case n2r is the kernel of the natural homomorphism of 7r2 into the 2-dimensional integral homology group of X. Comparing this with recent results of Hopf5 yields numerous examples of spaces with k3 $ 0. 5. Generalizations.-1°: The construction of k3 generalizes in an obvious fashion to yield a cohomology class kn+1 e Hn+l(irj, 7r,,), provided that 7ri = 0 for 1 < i < n...
متن کاملa contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
Invariant curves and semiconjugacies of rational functions
Jordan analytic curves which are invariant under rational functions are studied.
متن کاملDistinguishing Embedded Curves in Rational Complex Surfaces
We construct many pairs of smoothly embedded complex curves with the same genus and self-intersection number in the rational complex surfaces CP 2#nCP 2 with the property that no self-diffeomorphism of CP 2#nCP 2 sends one to the other. In particular, as a special case we answer a question originally posed by R. Gompf (1995) concerning genus two curves of selfintersection number 0 in CP 2#13CP .
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
