The Journal of the Tensor Society (JTS) is the official organ of The Tensor Society and publishes original research articles in differential geometry, relativity, cosmology, and all interdisciplinary areas in mathematics that utilize differential geometric methods and structures. The following main areas are covered: differentiable manifolds, Finsler geometry, Lie groups, local and global differential geometry, General Relativity, and geometric theories of gravitation; cosmology, dark energy, dark matter, the accelerating universe, geometric models for particle physics; supergravity and supersymmetric field theories; classical and quantum field theory; gauge theories; topological field theories; and the geometry of chaos. In addition to original research, the Journal of the Tensor Society also publishes focused review articles that assess the state of the art, identify upcoming challenges, and propose promising solutions for the community.
