O-minimal spectra, infinitesimal subgroups and cohomology
By recent work on some conjectures of Pillay, each definably compact group G in a saturated o-minimal expansion of an ordered field has a normal “infinitesimal subgroup” G such that the quotient G/G, equipped with the “logic topology”, is a compact (real) Lie group. Our first result is that the functor G 7→ G/G sends exact sequences of definably compact groups into exacts sequences of Lie group...
متن کاملMapeamento Participativo de Opiniões sobre o Uso de Dinheiro Público
Recent surveys show dissatisfaction of the population with politicians and their representatives. This paper describes a technological tool developed to provide a communication channel between citizens and policy makers. This tool allows to make reports like the lack of investment and waste of public resources, and highlight initiatives which has society approval. The reports will be georeferen...

متن کاملHistograms of Infinitesimal Neighbourhoods
Image analysis methods that use histograms defined over non-zero-sized local neighbourhoods have been proposed [1-4]. To better understand such methods, one can study the histograms of infinitesimal neighbourhoods. In this paper we show how the properties of such histograms can be derived through limit arguments. We show that in many cases the properties of these histograms are given by simple ...
متن کاملO ct 1 99 7 ON THE INFINITESIMAL RIGIDITY OF HOMOGENEOUS VARIETIES
Let X ⊂ P N be a variety (respectively a patch of an analytic subman-ifold) and let x ∈ X be a general point. We show that if the projective second fundamental form of X at x is isomorphic to the second fundamental form of a point of a Segre P n × P m , n, m ≥ 2, a Grassmaniann G(2, n + 2), n ≥ 4, or the Cayley plane OP 2 , then X is the corresponding homogeneous variety (resp. a patch of the c...
