Finite linear simplex combinations {complex, topology} can meet or not meet in common faces. Complexes have values {characteristic, complex} found by formulas {Euler-Poincaré formula}. Complexes {chain, simplex} {simplex chain} can be linear oriented-simplex combinations. Boundary of chain boundary equals zero.
