Exponential Absolute Minimizing extension and biased infinity Laplacian

Yang Chu

We study the variational structure of the biased infinity Laplacian by introducing a notion of the $β$ \textit{-Exponential Absolute Minimizing Extension} ( $β$ --AM) on arbitrary len…

On the convexity for the range set of two quadratic functions

Huu-Quang Nguyen, Ya-Chi Chu, Ruey-Lin Sheu

Given $n \times n$ symmetric matrices $A$ and $B$ , Dines in 1941 proved that the joint range set ${(x^{T} A x, x^{T} B x) ∣ x \in R^{n}}$ is always convex. Our paper is concerned with…
