The expression surj_on f A B asserts that, viewed as a function defined on elements of A, the function f is surjective onto the set B.With these notions in hand, we can prove that the composition of injective functions is injective. The proof is similar to the one above, though now ...
Let X be a complex analytic manifold, and ψ an analytic function on X. Then there exists a complex analytic manifold M and a proper surjective map π : M → X such that the restriction of π onto the c...S. Encinas, O. Villamayor, A new proof of desingularization over fields of...

We define function \mathrm{toNatural}: \mathcal{M}(\{\mathrm{suc}\}, \circ) \to \mathbb{N},\\ m_1 \mapsto m_1(0),\\ and require \mathrm{suc} to be defined such that \mathrm{toNatural} is bijective. In other words, every different or new element of \mathcal{M}(\{\mathr...

A domain D is dictatorial iff there exists no surjective, strategy-proof and non-dictatorial social choice function defined over D. A dictatorial domain D is superdictatorial iff every superdomain of D is also dictatorial. The existence of dictatorial but not superdictatorial domains being known, ...
