Invariant structures on homogeneous manifolds are of fundamental importance in differential geometry. Recall that an affinor structure F (i.e., a tensor field F of type (1,1)) on a homogeneous manifold G/H is called invariant (with respect to G) if for any g ∈ G we have dτ(g)◦F = F ◦dτ(g), where τ(g)(xH)= (gx)H . An important place among homogeneous manifolds is occupied by homogeneousΦ-spaces ...

Even small, taken-for- granted words can have a strong influence on the pedagogical effect of writing conference. In this study, we examined how experienced and trained center tutors’ use discourse marker so helped them to connect ideas manage their conferences with students. We extent which six types varied according English L1 (EL1)/ L2 (EL2) status interlocutor. studied 26 conferences: 13 in...
