Kawamata-Miyaoka-type inequality for $\mathbb Q$-Fano varieties with canonical singularities II: Terminal $\mathbb Q$-Fano threefolds [PDF]

Épijournal de Géométrie Algébrique
We prove an optimal Kawamata-Miyaoka-type inequality for terminal $\mathbb Q$-Fano threefolds with Fano index at least $3$. As an application, any terminal $\mathbb Q$-Fano threefold $X$ satisfies the following Kawamata-Miyaoka-type inequality \[ c_1(X ...

Computation of a Reference Model for Robust Fault Detection and Isolation Residual Generation

Journal of Control Science and Engineering, 2008
This paper considers matrix inequality procedures to address the robust fault detection and isolation (FDI) problem for linear time-invariant systems subject to disturbances, faults, and polytopic or norm-bounded uncertainties.

On some inequality of Hermite-Hadamard type [PDF]

Opuscula Mathematica, 2012
It is well-known that the left term of the classical Hermite-Hadamard inequality is closer to the integral mean value than the right one. We show that in the multivariate case it is not true.

Optimal Szegö-Weinberger type inequalities

Communications on Pure and Applied Analysis, 2016
Denote with $μ_{1}(Ω;e^{h\left(|x|\right)})$ the first nontrivial eigenvalue of the Neumann problem \begin{equation*} \left\{\begin{array}{lll} -\text{div}\left(e^{h\left(|x|\right)}\nabla u\right) =μe^{h\left(|x|\right)}u & \text{in} & Ω& & \frac{\partial u}{\partial ν}=0 & \text{on} & \partial Ω, \end{array} \right.

Linear programming with inequality constraints via entropic perturbation

International Journal of Mathematics and Mathematical Sciences, 1996
A dual convex programming approach to solving linear programs with inequality constraints through entropic perturbation is derived. The amount of perturbation required depends on the desired accuracy of the optimum.

Getting to a feasible income equality.

PLoS ONE, 2021
Income inequality is known to have negative impacts on an economic system, thus has been debated for a hundred years past or more. Numerous ideas have been proposed to quantify income inequality, and the Gini coefficient is a prevalent index.

Finding Minimal Solution to Generalized Min-Max Programming Problem With Addition-Min Composition

IEEE Access
In order to describe the data transmission mechanism in the BitTorrent-like peer-to-peer file-sharing system, the addition-min fuzzy relation inequality system is introduced. At the same time, in order to distinguish the different importance of different

Estimation of Optimal Commodity Tax Rates in Iran [PDF]

Faslnāmah-i Pizhūhish/Nāmah-i Iqtisādī, 2008
This study estimates optimal commodity tax rates regarding efficiency and social justice. A many- person Ramsey rule and Bergson – Samuelson social welfare function are used for estimating optimal tax rates.
