Convexity in maths
WebConvexity in polygons refers to the direction in which the vertices of a polygon are pointing, which can be outwards or inwards. In this article, we will define what a convex polygon is, and its properties, and we will show you some examples of convex polygons that you can find in the real world. We will also explain the differences between ... WebHessian matrix. In mathematics, the Hessian matrix or Hessian is a square matrix of second-order partial derivatives of a scalar-valued function, or scalar field. It describes the local curvature of a function of many variables. The Hessian matrix was developed in the 19th century by the German mathematician Ludwig Otto Hesse and later named ...

In this article, we will define what a convex polygon … WebWe study several notions of abstract convexity in graphs and hypergraphs. In each case, we obtain analogues of several classical results, including the Minkowski–Krein–Milman theorem, Caratheodory’s theorem and Tietze’s convexity theorem. In addition, our results yield new characterizations of the classes of chordal gaphs, strongly chordal graphs, …

WebIn mathematics, the modulus of convexity and the characteristic of convexity are measures of "how convex " the unit ball in a Banach space is. In some sense, the modulus of convexity has the same relationship to the ε - δ definition of uniform convexity as the modulus of continuity does to the ε - δ definition of continuity .

WebConcavity relates to the rate of change of a function's derivative. A function f f is concave up (or upwards) where the derivative f' f ′ is increasing. This is equivalent to the derivative of f' f ′, which is f'' f ′′, being positive. Similarly, f f is concave down (or downwards) where the derivative f' f ′ is decreasing (or ... austin 1983WebConvexity definition, the state of being convex.
