Without the fortress, without the family, without a home...what's left is the Absolute Man of Steel! Spiraling out of the catastrophic events of Absolute Power, a new side of the DC Universe is born--the Absolute Universe! In a different, darker world, Kal-El landed in a remote Kansas field, the last survivor from an alien planet...but even before that moment, nothing unfolded as you'd expect. As he tries to survive in a world seemingly determined to repeat the mistakes of the demolished Krypton, he'll come into conflict with the globe-straddling Lazarus Corporation and its agenda of exploitation...and go fist-to-fist with its brutal army of Peacemakers! Best-selling writer Jason Aaron (Star Wars, Thor, Teenage Mutant Ninja Turtles) is joined by superstar artist Rafa Sandoval (The Flash, Action Comics) to reinvent Superman from the ground up! Collects Absolute Superman #1-6.

It provides solid foundations for further study in mathematics in general, and topology in particular.Aimed at undergraduate students in mathematics with no previous exposure to topology, the book presents key concepts in a mathematically rigorous yet accessible manner, illustrated by numerous examples.

The study of surfaces with constant mean curvature (CMC) is one of the main topics in classical differential geometry. Moreover, CMC surfaces are important mathematical models for the physics of interfaces in the absence of gravity, where they separate two different media or for capillary phenomena. Further, as most techniques used in the theory of CMC surfaces not only involve geometric methods but also PDE and complex analysis, the theory is also of great interest for many other mathematical fields.While minimal surfaces and CMC surfaces in general have already been treated in the literature, the present work is the first to present a comprehensive study of “compact surfaces with boundaries,” narrowing its focus to a geometric view. Basic issues include the discussion whether the symmetries of the curve inherit to the surface; the possible values of the mean curvature, area and volume; stability; the circular boundary case and the existence of the Plateau problem in the non-parametric case. The exposition provides an outlook on recent research but also a set of techniques that allows the results to be expanded to other ambient spaces. Throughout the text, numerous illustrations clarify the results and their proofs.The book is intended for graduate students and researchers in the field of differential geometry and especially theory of surfaces, including geometric analysis and geometric PDEs. It guides readers up to the state-of-the-art of the theory and introduces them to interesting open problems.
