On tangent cones at infinity of algebraic varieties [PDF]

open access: yes, 2018
In this paper, we define the geometric and algebraic tangent cones at infinity of algebraic varieties and establish the following version at infinity of Whitney’s theorem [Local properties of analytic varieties, in Differential and Combinatorial ...

A tangent cone analysis of smooth preferences on a topological vector space [PDF]

open access: yes
A theory of smooth preferences on a locally convex, topological vector space is developed by characterizing the existence of a unique supporting hyperplane to a convex set at a given point. The results are expressed in terms of the tangent cone.

Calculating tangent sets to certain sets in functional spaces [PDF]

open access: yes, 1997
We give necessary and sufficient conditions for a given element to be a member of the second order tangent set $T»_{K}(f,v)$ to the positive cone $K$ in $L^{\infty}¸.$ Since, in general $T»_{K}(f,v)$ may be empty we give conditions on functions $f¸, v ...

An ABS-GA Algorithm for Solving Fuzzy Optimization Problems

open access: yesFuzzy Optimization and Modeling
This paper presents a fuzzy programming model with LR fuzzy coefficients. To solve it efficiently, we propose a novel hybrid ABS-GA algorithm that synergistically combines the ABS algorithm for dimensionality reduction with a Genetic Algorithm (GA ...

Fields of tangent sets and hofmann cones

open access: yesSemigroup Forum, 1986
The Bony-Brezis theorem states that a closed subset F of a differentiable manifold M is invariant under the flow associated with a locally Lipschitzian vector field A if and only if for every \(p\in F\) the tangent vector A(p) belongs to the subtangent space of F at p.

Oxidative Stability and Rheological Features in Recycled Composites Based on Postconsumer Polypropylene and Antioxidant‐Loaded Silicas

open access: yesPolymer Engineering &Science, EarlyView.
Role of antioxidant supported on MCM‐41 and nano‐silica in enhancing oxidation induction time (OIT) and nucleation performance. ABSTRACT Plastic recycling efforts are hindered by the reduction of material properties in recyclates stemming from oxidative degradation of their polymeric chains.
