On the Number of Connected Components of the Parabolic Curve
نویسنده
چکیده
We construct a polynomial of degree d in two variables whose Hessian curve has (d − 2) connected components using Viro patchworking. In particular, this implies the existence of a smooth real algebraic surface of degree d in RP 3 whose parabolic curve is smooth and has d(d− 2) connected components. “Salut à toi Che Guevara”

In order to investigate the milk and its components curve of Khuzestani buffaloes a total of 9061 data of test-day milk, fat and protein yield of the first lactation period buffaloes collected during 1993-2013 were used. The buffaloes having less than 4 test-day records were removed. The lactation days was considered from the 5th to 210th days of lactation. Five different functions of Wood, Wil...
متن کاملA Survey On the Vulnerability Parameters of Networks
The analysis of vulnerability in networks generally involves some questions about how the underlying graph is connected. One is naturally interested in studying the types of disruption in the network that maybe caused by failures of certain links or nodes. In terms of a graph, the concept of connectedness is used in dierent forms to study many of the measures of vulnerability. When certain vert...
متن کاملModuli Spaces of Parabolic Higgs Bundles and Parabolic K(d) Pairs over Smooth Curves: I
This paper concerns the moduli spaces of rank two parabolic Higgs bundles and parabolic K(D) pairs over a smooth curve. Precisely which parabolic bundles occur in stable K(D) pairs and stable Higgs bundles is determined. Using Morse theory, the moduli space of parabolic Higgs bundles is shown to be a noncompact, connected, simply connected manifold, and a computation of its Poincaré polynomial ...
متن کاملA note on blow-up in parabolic equations with local and localized sources
This note deals with the systems of parabolic equations with local and localized sources involving $n$ components. We obtained the exponent regions, where $kin {1,2,cdots,n}$ components may blow up simultaneously while the other $(n-k)$ ones still remain bounded under suitable initial data. It is proved that different initial data can lead to different blow-up phenomena even in the same ...
متن کاملParameter determination in a parabolic inverse problem in general dimensions
It is well known that the parabolic partial differential equations in two or more space dimensions with overspecified boundary data, feature in the mathematical modeling of many phenomena. In this article, an inverse problem of determining an unknown time-dependent source term of a parabolic equation in general dimensions is considered. Employing some transformations, we change the inverse prob...
