"Convex" characterization of linearly convex domains [PDF]

open access: yesMATHEMATICA SCANDINAVICA, 2011
We prove that a $C^{1,1}$-smooth bounded domain $D$ in $\C^n$ is linearly convex if and only if the convex hull of any two discs in $D$ with common center lies in $D.$Comment: to appear in Math.

Convex Functions on Convex Polytopes [PDF]

open access: yesProceedings of the American Mathematical Society, 1968
The behavior of convex functions is of interest in connection with a wide variety of optimization problems. It is shown here that this behavior is especially simple, in certain respects, when the domain is a polytope or belongs to certain classes of sets closely related to polytopes; moreover, the polytopes and related classes are actually ...

Convex Biclustering [PDF]

open access: yesBiometrics, 2016
SummaryIn the biclustering problem, we seek to simultaneously group observations and features. While biclustering has applications in a wide array of domains, ranging from text mining to collaborative filtering, the problem of identifying structure in high-dimensional genomic data motivates this work.

On Column-Convex and Convex Carlitz Polyominoes [PDF]

open access: yesMathematics in Computer Science, 2021
In this paper, we introduce and study {\it Carlitz polyominoes}. In particular, we show that, as $n$ grows to infinity, asymptotically the number of \begin{enumerate} \item column-convex Carlitz polyominoes with perimeter $2n$ is \beq \frac{9\sqrt{2}(14+3\sqrt{3})}{2704\sqrt{ n^3}}4^n. \feq \item convex Carlitz polyominoes with perimeter $2n$ is \beq \

On the moduli of convexity [PDF]

open access: yesProceedings of the American Mathematical Society, 2007
[EN] It is known that, given a Banach space (X, parallel to center dot parallel to), the modulus of convexity associated to this space delta X is a non-negative function, nondecreasing, bounded above by the modulus of convexity of any Hilbert space and satisfies the equation delta x(epsilon)/epsilon(2)

On φ-convexity of convex functions

open access: yesLinear Algebra and its Applications, 1998
The authors construct a non-trivial set \(\Phi\) of extended-real valued functions on \(R^n\) containing all affine functions, such that an extended-real valued function defined on \(R^n\) is convex if and only if it is \(\Phi\)-convex, i.e., it is the pointwise supremum of some subset of \(\Phi\). They also prove a new sandwich theorem.

The extensive 1-median problem with radius on networks [PDF]

open access: yesOpuscula Mathematica, 2023
