Tropical intersection theory, and real inflection points of real algebraic curves

asymptoti theory of global elds (that is number elds or funtion elds) and v arieties over.. them are quite diverse

We illustrate the general theory with a discussion of real hyper-elliptic curves in paragraph 6, real plane curves in paragraph 7, and real trigonal curves in paragraph 8, and end

Furthermore, there is another phenomenon which is due to the principle of analytic continuation and which is quite well known (cf. [16]): the local and the global CR-orbits

The present paper is dedicated to the study of the normalization of real algebraic varieties, together with the integral closure of natural rings of functions on real

The following theorem gives an upper bound on the number of non-real fixed points of an automorphism in terms of the number of connected component of the real part of the

We address the problem of the maximal finite number of real points of a real algebraic curve (of a given degree and, sometimes, genus) in the projective plane.. We improve the

Using some more arguments from real algebraic geometry one can also reduce the problem of computing a finite set of points guaranteed to meet every semi-algebraically

Finally Christian Duhamel sent me a correspondence he had with the Scientific Attaché at the French Embassy in Tehran, Bernard Paqueteau, who was looking for a scientific advice for
