... Within the well-formed formulas are singled out certain ones, called theorems, by specifying axioms and the notion of proof. The axioms, for example, would assert that " =" is an equivalence relation and " •" a quasigroup. Moreover, the logical operations ~ (not), A (and), V (or), = (equivalent), ca ...

... DM(S) can be constructed from the “naive” version Amot (SmS )0 , i.e., we may replace all the homotopy identities in the construction of the motivic DG tensor category A mot (SmS ) with strict identities. Combining this with (3.2.6), we arrive at a construction of Dbmot (S) as a localization of the ...

... b ∈ B, there is an a ∈ A such that f (a) = b. We say f is a bijection if f is both injective and surjective. If f : A → B is one-to-one, then we can define the inverse f −1 : range(f ) → A of f by f (b) = a where a is the unique element of A such that f (a) = b. In particular, if f : A → B is a bije ...

In contrast, our rst main result shows that there is a way to add reachability and a vast number of other topological queries while retaining closure. In fact, for any set T of topological properties, we ...

Homomorphism

In abstract algebra, a homomorphism is a structure-preserving map between two algebraic structures (such as groups, rings, or vector spaces). The word homomorphism comes from the ancient Greek language: ὁμός (homos) meaning ""same"" and μορφή (morphe) meaning ""form"" or ""shape"". Isomorphisms, automorphisms, and endomorphisms are special types of homomorphisms.
