A chain homotopy offers a way to relate two chain maps that induce the same map on homology groups, even though the maps may be different. Given two chain complexes A and B, and two chain maps f, g : A → B, a chain homotopy is a sequence of homomorphisms h n : A n → B n+1 such that hd A + d B h = f − g. The maps may be written out in a ...

The boundary of a chain is the linear combination of boundaries of the simplices in the chain. The boundary of a k-chain is a (k−1)-chain. Note that the boundary of a simplex is not a simplex, but a chain with coefficients 1 or −1 – thus chains are the closure of simplices under the boundary operator.
The general algebraic modeling system (GAMS) is a high-level modeling system for mathematical optimization. GAMS is designed for modeling and solving linear, nonlinear, and mixed-integer optimization problems. The system is tailored for complex, large-scale modeling applications and allows the user to build large maintainable models that can be ...
The following templates and functions configure the system in some way: Module:Autotaxobox | topLevelTaxon – defines which taxa act as the very top level of the taxonomic hierarchy (e.g. "Life") {{ Taxobox colour }} – defines which taxa set the taxobox colour and what those colours are (also used in manual taxoboxes)
A relatively common and simple toolchain consists of the tools to build for a particular operating system (OS) and CPU architecture; consisting of a compiler, a linker, and a debugger. With a cross-compiler, a toolchain can support cross-platform development. For building more complex software systems, many other tools may be in the toolchain.
The Integrated Database Management System (IDMS) is a network model database management system for mainframes.It was first developed at B.F. Goodrich and later marketed by Cullinane Database Systems (renamed Cullinet in 1983).
The seven management and planning tools have their roots in operations research work done after World War II and the Japanese total quality control (TQC) research. [ 1 ] [ 2 ] The New seven tools
