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 ...

In homological algebra, the mapping cone is a construction on a map of chain complexes inspired by the analogous construction in topology.In the theory of triangulated categories it is a kind of combined kernel and cokernel: if the chain complexes take their terms in an abelian category, so that we can talk about cohomology, then the cone of a map f being acyclic means that the map is a quasi ...
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.
A Wardley map is a map for business strategy. [1] Components are positioned within a value chain and anchored by the user need, with movement described by an evolution axis. [ 2 ] Wardley maps are named after Simon Wardley who created the technique at Fotango in 2005 having created the evolutionary framing the previous year.
The first Canadian virtual reality film festival was the FIVARS Festival of International Virtual & Augmented Reality Stories, founded in 2015 by Keram Malicki-Sánchez. [131] In 2016, the first Polish VR program, The Abakanowicz Art Room was realized – it documented the art office of Magdalena Abakanowicz , made by Jarosław Pijarowski and ...
A join may have two or more incoming control flows and one outgoing control flow. A join synchronizes all activated incoming control flows. In the Event-driven Process Chain diagram how the concurrency achieved is not a matter. In reality the concurrency can be achieved by true parallelism or by virtual concurrency achieved by interleaving.
Event chain methodology is an uncertainty modeling and schedule network analysis technique that is focused on identifying and managing events and event chains that affect project schedules. Event chain methodology is the next advance beyond critical path method and critical chain project management.
