Orientations and Transfers in Cohomology of Algebraic Varieties
Algebro-geometric cohomology theories are described axiomatically, with a systematic treatment of their orientations. For every oriented theory, transfer mappings are constructed for mappings of smooth varieties that are proper on supports. In some basic cases, transfers are calculated. The presentation is illustrated by motivic cohomology, K-theory, algebraic cobordism, and other examples. The...
متن کاملIncompressibility of Products of Weil Transfers of Generalized Severi-brauer Varieties
We generalize the result of [11] on incompressibility of Galois Weil transfer of generalized Severi-Brauer varieties, to direct products of varieties of such type; as shown in [11], this is needed to compute essential dimension of representations of finite groups. We also provide a generalization to non-Galois (separable) Weil transfer.
متن کاملcomparison of pregnancy rate between fresh embryo transfers and frozen-thawed embryo transfers following icsi treatment
background: the use of assisted reproductive technology (art) is increasing in the world. the rate, efficacy and safety of art are very different among countries. there is an increase in the use of intra cytoplasmic sperm injection (icsi), single fresh embryo transfer (et) and frozen-thawed embryo transfer (fet). objective: the objective of this study was to compare pregnancy rate in fresh et a...
متن کاملVector Fields and Transfers
For a smooth fibre bundle F i −→ E p −→ B where F is a compact manifold with or without boundary, a vertical vector field V gives rise to a transfer τ V as an S-map. Our goal is to show these transfers satisfy an equation analogous to one that the index of vector fields satisfy. This equation gives results involving equivariant vector fields as well as a characterization of those transfers defi...
متن کاملIntergenerational Transfers and Growth
This paper shows that, when the supply side dynamics is modelled along the lines suggested by the endogenous growth literature, it is possible that properly designed unfunded schemes would promote growth. The reduction in savings when an intergenerational transfer programme is introduced has a negative impact on capital accumulation and output. However, in the long run the saving rate will be g...
