Publikováno v: Journal of Global Optimization. 82:659-689

In this work, we propose a new approach called “Successive Linear Programming Algorithm (SLPA)” for finding an approximate global minimizer of general nonconvex quadratic programs. This algorithm can be initialized by any extreme point of the con

This work concerns the northernmost limit of the West African Craton (WAC) and Variscan WAC-related terranes of NW Africa. Based on newly obtained radiometric age of an oceanic gabbro from the “Mesorif Suture Zone” of the External Rif Belt, we pr

Let A be a Banach algebra which does not contain any nonzero idempotent element, let γ > 0, and let \(x \in A\). We show that if \(\parallel x \parallel \geq \frac{log(\gamma + 1)}{\gamma},\) then \(\parallel e^{x} - e^{(\gamma+1)x} \parallel \geq \

K-richterite/phlogopite-bearing peridotite xenoliths and MARID inclusions have been found in Late Cretaceous (67±0.2 million years) monchiquites and an olivine nephelinite from North Eastern Morocco. It is the first evidence of MARID rocks and K-ric
