Generalized Concavity deals with the many nonconcave functions that have properties similar to those of concave functions. Specific topics covered in this book include: a review of concavity and the basics of generalized concavity; applications of generalized concavity to economics. Hence, the focus of the first part of the book is concerned with several types of generalized convex sets Generalized concavity book generalized concave functions.

In mathematics, a quasiconvex function is a real-valued function defined on an interval or on a convex subset of a real vector space such that the inverse image of any set of the form (− ∞,) is a convex a function of a single variable, along any stretch of the curve the highest point is one of the endpoints.

The negative of a quasiconvex function is said to be quasiconcave.

Concavity. The second derivative of a function f measures the concavity of the graph of f.A function whose second derivative is positive will be concave up (also referred to as convex), meaning that the tangent line will lie below the graph of the function.

Similarly, a function whose second derivative is negative will be concave down (also simply called concave), and its tangent lines will. Analyzing Concavity of a Function. Calculus Graphing with the Second Derivative Analyzing Concavity of a Function.

Key Questions. How do you determine the concavity of a quadratic function. For a quadratic function #f(x)=ax^2+bx+c#, if #a>0#, then #f# is concave upward everywhere, if #a. This paper examines properties and interrelations of several concepts of generalized concavity.

It shows that the class of functions that are both “generalized concave” and “generalized convex” is closely related to the class of monotone functions of a single by: Downloadable. In a less widely known contribution, Béla Martos (, Hungarian Academy of Sciences) introduced a generalized notion of concavity that is closely related to what is nowadays known as r-concavity in the operations research literature, and that is identical to what is nowadays known as ρ-concavity in the economics literature.

An inflection point is a point on a curve at which the concavity changes sign from plus to minus or from minus to plus. • the conjugate function • quasiconvex functions • log-concave and log-convex functions • convexity with respect to generalized inequalities 3–1. Definition f: Rn → R is convex if domf is a convex set and f(θx+(1−θ)y) ≤ θf(x)+(1−θ)f(y) for all x,y ∈ domf, 0 ≤ θ ≤ 1.

We can find the concavity of a function by finding its double derivative (#f''(x)#) and where it is equal to zero. Let's do it then. #f(x)=mx+b# #=>f'(x)=m*1*x^()+0# #=>f'(x)=m*1# #=>f'(x)=m# #=>f''(x)=0# So this tells us that linear functions have to curve at every given point.

Math video on how to determine intervals of concavity and find inflection points of a polynomial by performing the second derivative test. Inflection points exist where the second derivative is 0 or undefined and concavity can be determined by finding decreasing or increasing first derivatives.

Problem 1. Downloadable (with restrictions). Generalized order statistics have been introduced as a unification of several models of random variables arranged in ascending order of magnitude with different interpretations and statistical applications.

The purpose of this note is to investigate conditions on the underlying distribution function and on the parameters under which the generalized order. Thus the concavity changes where the second derivative is zero or undefined. Such a point is called a point of inflection.

The procedure for finding a point of inflection is similar to the one for finding local extreme values: (1) find where the second derivative is zero or undefined, (2) determine that the sign of the second derivative.

3 Early notions of generalized concavity Research on generalized convex and concave functions has a long tradition in both mathematics and operations research. The in uential book by Hardy et al. () introduces generalized means, which appear also in the de nition of by: 4. Concavity of the function can be used also to determine if there is an extreme value or not at a critical point of f.

Note that a function with a relative minimum is concave up on an interval around it. Similarly, a function with a relative maximum is concave down on an interval around it.

Thus, if File Size: 1MB. This paper is from an unpublished typescript from the University of North Carolina (). When confronted with additivity, it is far more convenient to use profit functions than cost functions or indirect utility functions. The reason for this is that if the objective function is additive then the resulting profit function is also additive, so one does not lose all of the explicit original.

The degree of concavity varies, however, depending on a set of physical conditions that can be identified by a set of dimensionless numbers. A comparison of these numbers reveals the relative importance of the driving mechanisms for concavity. A condition for concavity driven by the fourth mechanism, that is, tributary input, is by: a good body of results and applications on generalized convexity, so they decided to publish a book under the title \Generalized Concavity".

The book appeared 8 years later in Plenum Press. It was a great success, so SIAM decided to include it in its series Classics in Applied Mathematics, and the book appeared again in Generalized concavity in cooperative game theory: characterizations in terms of the core: Published in: Generalized convexity.
