Space-Time Structure: Algebra and geometry

The present volume contains selected articles published in the scientific journal «Hypercomplex Numbers in Geometry and Physics» (numbers 1-6). The topics covered by the included contributions range from hypercomplex algebras to associated Finsler geometries, focusing on the commutative-associative algebras and on Berwald-Moor metric structures, applications of polynumber algebras in Physics, and Finslerian extensions of Relativity Theory.
