In this paper, we study the nonconvex quadratic convex–concave minimax fractional optimization problem (P). First, based on the S-lemma and the convex Farkas lemma, we transform (P) into a generalized ...

To control light, curved lenses are used today, that are often made of glass that is either concave or convex, which refracts the light in different ways. These types of lenses can be found in ...

Complicating the potential partnership between math and AI is the fact that how kids learn math is a very personal experience—with some mastering concepts much quicker than others. Average or ...

Convex Group Ltd, the Bermudian-headquartered international specialty insurer and reinsurer, has received in-principle approval to launch Lloyd’s Syndicate 1984, which will commence underwriting ...

OK, I will ride. Life is a spectrum of colours that viewers view through convex and concave lenses. Lo, I will not judge, lest I be judged, because everyone has the right to their views.

Light passes through a series of convex and concave glass elements in a tube assembly and can be focused into the eyepiece for viewing distant objects.

Work out equations and draw graphs with this useful new tool. In Apple's great 2024 software refresh—specifically iOS 18, iPadOS 18, and macOS 15 Sequoia—a new tool called Math Notes was added ...

Chief Justice John G. Roberts Jr. referred to math — specifically to the efficiency gap, a mathematical measure of gerrymandering — as “a bunch of baloney” and “sociological gobbledygook.” ...

In this correspondence, we give several inherent properties of the capacity function of a Gaussian channel with and without feedback by using some operator inequalities and matrix analysis. We give a ...

Many students suffer from math anxiety. Steven Errico/DigitalVision via Getty Images 1. Foster positive math identities 2. Modernize math content 3. Align state policies and requirements: ...
