p-ADIC PERIODS AND DERIVED DE RHAM COHOMOLOGY
نویسنده
چکیده
For a smooth variety X over a base field of characteristic 0 we have its algebraic de Rham cohomology H · dR(X) := H (XZar,Ω · X); for nonsmooth X, one defines H · dR(X) using cohomological descent as in Deligne [D]. If the base field is C, then one has the Betti cohomology H · B(X) := H (Xcl,Q) and a canonical period isomorphism (“integration of algebraic differential forms over topological cycles”)

According to Kontsevich's Homological Mirror Conjecture [K1], a mirror pair, X a ˆ X, of Calabi-Yau manifolds has two associated A ∞-categories, the derived category of coherent sheaves on X and the Fukaya category ofˆX, equivalent. In particular, the moduli spaces of A ∞-deformations of these two categories must be isomorphic implying Another expected corollary is the equivalence of two Froben...

I Francesco Baldassarri (Università di Padova) Title: Non-archimedean analysis of irregular singularities Abstract: Let X be a smooth algebraic surface over the complex field C, and Z be a divisor with normal crossings in X. Sabbah’s conjecture on the existence of a good formal structure for an integrable connection on X with poles along Z, has been proved independently by Kiran Kedlaya and Tak...

Objective(s): Glial cell line-derived neurotrophic factor (GDNF) can effectively promote axonal regeneration，limit axonal retraction，and produce a statistically significant improvement in motor recovery after spinal cord injury (SCI). However, the role in primate animals with SCI is not fully cognized. Materials and Methods:18 healthy juvenile rhesuses were divided randomly into six groups, obs...
متن کاملThe Bacteriophage Carrier State of Campylobacter jejuni Features Changes in Host Non-coding RNAs and the Acquisition of New Host-derived CRISPR Spacer Sequences
Incorporation of self-derived CRISPR DNA protospacers in Campylobacter jejuni PT14 occurs in the presence of bacteriophages encoding a CRISPR-like Cas4 protein. This phenomenon was evident in carrier state infections where both bacteriophages and host are maintained for seemingly indefinite periods as stable populations following serial passage. Carrier state cultures of C. jejuni PT14 have gre...

Background and Objective: Nowadays, although umbilical cord blood is a commonly used source of hematopoietic stem cell, its low frequency of these cells is the main factor limiting its clinical application. The transplantation of hematopoietic stem cells derived from placenta tissue along with umbilical cord blood cells of the same sample may be an appropriate approach to solve this problem. In...
