Sequential optimality conditions have played a major role in establishing strong global convergence properties of numerical algorithms for many classes of optimization problems. In particular, the way complementarity is handled defines different optimality conditions and is fundamental to achieving a strong condition. Typically, one uses the inner product structure to measure complementarity, which provides a general approach to conic optimization problems, even in the infinite-dimensional case. In this paper we exploit the Jordan algebraic structure of symmetric cones to measure complementarity, resulting in a stronger sequential optimality condition related to the well-known complementary approximate Karush-Kuhn-Tucker conditions in standard nonlinear programming. Our results improve some known results in the setting of semidefinite programming and second-order cone programming in a unified framework. In particular, we obtain global convergence that are stronger than those known for augmented Lagrangian and interior point methods for general symmetric cones.

Leishmaniasis and Chagas diseases affect millions of people, particularly in developing countries, with conventional treatments proving unsatisfactory due to increasing drug resistance and high toxicity. Therefore, there is an urgent need for new drugs to combat neglected tropical diseases (NTDs). In this st

This article reflects on the barriers faced in determining prices for georeferencing services for rural properties in Brazil. The lack of widely accepted objective criteria creates difficulties for both professionals in the field and landowners. Throughout the text, a review of the Georeferencing of Rural Properties and its evolution over the years is conducted, analyzing conventional pricing methodologies and their limitations. It highlights that the time required for service execution is a fundamental element in defining fair values to be charged or paid. The research suggests that the predictability of work time should be the primary factor in formulating more accurate prices, recommending the viability of a geospatial model, which will be addressed in a future article.

We present a bijection between torsion pairs in $$\text {coh}(\mathbb )$$ with corresponding t-structures in $$\textrm{D}^{b}(\text {coh}(\mathbb {X}))$$ where $$\mathbb {X}$$ represents a weighted projective line. When focusing on the split case, we derive a bijection between this class and corresponding torsion pairs in the module category of a concealed canonical algebra. Additionally, we demonstrate that if the aisle of a split t-structure in the derived category of a hereditary category contains an Ext-projective object, then it admits a tilting complex. Finally, we use the structure of the Auslander-Reiten quiver of $$\textrm{D}^{b}(\text {coh}(\mathbb {X}))$$ in order to classify split t-structures in $$\textrm{D}^{b}(\text {coh}(\mathbb {X}))$$ .
