After the development of manifolds and algebraic varieties in the previous century, mathematicians and physicists have continued to advance concepts of space. This book and its companion explore various new notions of space, including both formal and conceptual points of view, as presented by leading experts at the New Spaces in Mathematics and Physics workshop held at the Institut Henri Poincaré in 2015. This volume covers a broad range of topics in mathematical physics, including noncommutative geometry, supergeometry, derived symplectic geometry, higher geometric quantization, intuitionistic quantum logic, problems with the continuum description of spacetime, twistor theory, loop quantum gravity, and geometry in string theory. It is addressed primarily to mathematical physicists and mathematicians, but also to historians and philosophers of these disciplines.
Tim Maudlin sets out a completely new method for describing the geometrical structure of spaces, and thus a better mathematical tool for describing and understanding space-time. He presents a historical review of the development of geometry and topology, and then his original Theory of Linear Structures.

This book presents a comprehensive review of the subject of gravitational effects in quantum field theory. Although the treatment is general, special emphasis is given to the Hawking black hole evaporation effect, and to particle creation processes in the early universe. The last decade has witnessed a phenomenal growth in this subject. This is the first attempt to collect and unify the vast literature that has contributed to this development. All the major technical results are presented, and the theory is developed carefully from first principles. Here is everything that students or researchers will need to embark upon calculations involving quantum effects of gravity at the so-called one-loop approximation level.
Historical surveys consider Judeo-Christian notions of space, Newtonian absolute space, perceptions from 18th century to the present, more. Numerous quotations and references. "Admirably compact and swiftly paced style." — Philosophy of Science.
This book investigates a discrete theory beyond space and time of QCD-entanglement that creates space-time. Quantum entanglement is known as the most striking property of electrodynamics. It provides both a foundation for quantum information technology and a challenge for theoretical physics. Unfortunately, the equations of motion for entangled systems, quantum jumps and similar phenomena are always conceived as models in space-time. Regardless, whether we consider a quantified local oscillator, a heterodyne detection model, a Bell inequality, a CHSH-inequality, an objective pure state system, or a non-linear steering inequality, it is always formulated in space-time, using the x, σx and so on. This is a doubtable method, since proceeding in this way, we are constructing space-time models of those events that bring about this very space-time, the frames', wherein they are supposed to move. Those who carry out calculations in EPR quantum-steering experiments are acquainted with the Kochen-Specker theorem. But they are still deriving the estimates for expectation values of densities and inequalities from the implicit assumption of states in Hilbert-space. Though some of us have co-operatively managed to close all the major loopholes, the locality loophole, the freedom-of-choice loophole and the detection loophole, none of us has as yet realised that a closure of the locality-loophole in strong qcd-interaction is entirely impossible. A space-like separation of hadronic events cannot be achieved. The reason for our weak models is in the lack of a suitable exact theory of interaction. Such a theory is complete and phenomenologically consistent to some extent. Theoretically, both the iterant algebra of polarised entangled strings as well as the derived geometric algebra of the known space-time is incompatible with complete space-like separation. The loophole opening up on this basis is as large and as old as that universe we pretend to know.
