An abstraction of is defined by ,,, where is an abstraction mapping that maps every state in to a state in . [ 5 ] To preserve the critical properties of the model, the abstraction mapping maps the initial state in the original model s 0 {\displaystyle s_{0}} to its counterpart s 0 α {\displaystyle s_{0}^{\alpha }} in the abstract model.
The bundles on the X ij that we must control are V′ and V", the pullbacks to the fiber of V via the two different projection maps to X. Therefore, by going to a more abstract level one can eliminate the combinatorial side (that is, leave out the indices) and get something that makes sense for p not of the special form of covering with which ...
In computer science, abstract interpretation is a theory of sound approximation of the semantics of computer programs, based on monotonic functions over ordered sets, especially lattices. It can be viewed as a partial execution of a computer program which gains information about its semantics (e.g., control-flow , data-flow ) without performing ...
A bidirectional map is a related abstract data type in which the mappings operate in both directions: each value must be associated with a unique key, and a second lookup operation takes a value as an argument and looks up the key associated with that value.
Suppose first that / is simple, that is to say = for some .Let be any intermediate field between and , and let be the minimal polynomial of over .Let ′ be the field extension of generated by all the coefficients of .
