Solarities
Solarities: Elemental Encounters and Refractions is a transdiciplinary essay collection that explores the physical, conceptual, and political possibilities materialized by "solarity" - a form of relation to the sun and its elemental force upon planetary life. The authors propose that a different set of questions becomes possible when the material specificities of solar become the compass for thought, prompting us to uncover our relationship to the sun. How does solarity materialize in the bodies and lives of humans and non-humans now and in the future? What can we learn if we no longer take the sun for granted? How do we continue to persist on a planet that is so intimately bound up in a state of love, fear, and dependence on this primary source of all living energy? Each of the essays in Solarities take solar radiation as an interpretive lens that takes multiple forms, often transforming as it does so. Solarities draws inspiration from Black ecologies, Indigenous philosophy, feminist science & technology studies, and more-than-human discussions in the human sciences, recognizing the phenomenological and ontological openings they make available. The authors understand solarity as an energy source (channeled through photovoltaic cells, for example), but the essays gathered here focus on the lives that solarity creates or impedes. The experimental task is to find how solarities work their way into materials and processes across our work, seeking out the particular influences of solarity in making being(s). These relations are core to thinking the elemental conditions of solarity, since it is through particular forms of focalizing the sun that life is sustained, or made to wither, across the planet. In these ways, the elemental condition of solarity is at once hyper-particular and also shared across organic and inorganic bodies, conditioned by physical form and material composition. Throughout the collection, the authors explore how solarity appears or recedes from view when we concentrate our attentions on it, surfacing the existential omnipresence of the sun to open new thought possibilities, inspire new actions, and refract new dimensions of socionatural encounter.

A collective engages and mirrors the critical need for energy justice and transformation Solarities considers the possibilities of organizing societies and economies around solar energy, and the challenges of a just and equitable transition away from fossil fuels. Far from presenting solarity as a utopian solution to the climate crisis, it critically examines the ambiguous potentials of solarities: plural, situated, and often contradictory. Here, a diverse collective of activists, scholars, and practitioners critically engage a wide range of relationships and orientations to the sun. They consider the material and infrastructural dimensions of solar power, the decolonial and feminist promises of decentralized energy, solarian relations with more-than-human kin, and the problem of oppressive and weaponized solarities. Solarities imagines—and demands— possibilities for energy justice in this transition.
Geometric Approximation Theory
This monograph provides a comprehensive introduction to the classical geometric approximation theory, emphasizing important themes related to the theory including uniqueness, stability, and existence of elements of best approximation. It presents a number of fundamental results for both these and related problems, many of which appear for the first time in monograph form. The text also discusses the interrelations between main objects of geometric approximation theory, formulating a number of auxiliary problems for demonstration. Central ideas include the problems of existence and uniqueness of elements of best approximations as well as properties of sets including subspaces of polynomials and splines, classes of rational functions, and abstract subsets of normed linear spaces. The book begins with a brief introduction to geometric approximation theory, progressing through fundamental classical ideas and results as a basis for various approximation sets, suns, and Chebyshev systems. It concludes with a review of approximation by abstract sets and related problems, presenting novel results throughout the section. This text is suitable for both theoretical and applied viewpoints and especially researchers interested in advanced aspects of the field.
