On Fermionic T-duality of Sigma modes on AdS backgrounds
We study the fermionic T-duality symmetry of integrable Green-Schwarz sigma models on AdS backgrounds. We show that the sigma model on AdS5 × S1 background is self-dual under fermionic T-duality. We also construct new integrable sigma models on AdS2 ×CPn. These backgrounds could be realized as supercosets of SU supergroups for arbitrary n, but could also be realized as supercosets of OSp superg...
متن کاملSimultaneous versus Sequential Modes of Communication
This paper studies an organizational knowledge sharing process which requires costly "teaching" and "learning" e¤orts on the part of the sender and receiver, respectively. The process is a team problem in which the principal rewards successful communication by optimally rewarding performance. In this setting we compare two modes of communication with regard to e¢ ciency. The rst is sequential ...
متن کاملstatic versus dynamic assessment of l2 learners’ reading ability
dynamic assessment according to vygotskys sociocultural theory, states that instruction and assessment are interrelated. using static forms of assessment with second and foreign language students could do more harm than good. many teachers neglect to take account of the complexity involved in learning a second or foreign language and often wonder why learning of a language take so long. thi...
Low-Lying Fermion Modes: Dynamical versus Quenched
The eigenmodes of the Dirac operator carry information about the topological content of the background gauge field. The Atiyah-Singer index theorem tells us that in a sector with topological charge Qt the Dirac operator has at least |Qt| zero modes. In the presence of light dynamical fermions, the light quark determinant should suppress topological sectors with large |Qt|. As a consequence we e...
متن کاملthe effect of explicit versus implicit error correction on writing of iranian intermediate efl learners
در این پایان نامه دو روش اصلاح اشتباهات نوشتاری زبان آموزان بزرگسال ایرانی در سطح متوسط مورد بررسی قرار می گیرد. در روش اول (explicit) اشتباهات بطور مستقیم و در روش دوم (implicit) اشتباهات بصورت غیر مستقیم اصلاح می شود. برای انجام این تحقیق از دو گروه 15 نفری استفاده شده است. به زبان آموزان در هر جلسه یک موضوع انشا داده شده است. این کار در 15 هفته (15 جلسه) تکرار شده است. مقایسه نتایج این آزمون...
