Sommario/riassunto |
|
Beginning with a theoretical analysis of housing finance in the context of housing markets and financial intermediation generally, the authors then analyse, drawing on international experience, each of the main types of housing finance system: informal, deposit taking, contract and mortgage bank. Various aspects of the market are covered using examples drawn from the UK and elsewhere, including the regulatory framework, contemporary developments and securitization and secondary markets. Critical public policy issues, such as housing and the real economy, and housing subsidies, are analysed |

"In this article we propose a geometric description of Arthur packets for |

|
padic groups using vanishing cycles of perverse sheaves. Our approach is inspired by the 1992 book by Adams, Barbasch and Vogan on the Langlands classification of admissible representations of real groups and follows the direction indicated by Vogan in his 1993 paper on the Langlands correspondence. Using vanishing cycles, we introduce and study a functor from the category of equivariant perverse sheaves on the moduli space of certain Langlands parameters to local systems on the regular part of the conormal bundle for this variety. In this article we establish the main properties of this functor and show that it plays the role of microlocalization in the work of Adams, Barbasch and Vogan. We use this to define ABV-packets for pure rational forms of p-adic groups and propose a geometric description of the transfer coefficients that appear in Arthur's main local result in the endoscopic classification of representations. This article includes conjectures modelled on Vogan's work, including the prediction that Arthur packets are ABV-packets for p-adic groups. We gather evidence for these conjectures by verifying them in numerous examples"-- |
