Surjectivity in Fréchet Spaces [PDF]
Journal of Optimization Theory and Applications, 2019 We prove surjectivity result in Fréchet spaces of Nash-Moser type. That is, with uniform estimates over all semimorms. Our method works for functions which are only continuous and Gâteaux differentiable like in the recent result of Ekeland. We present the results in multi-valued setting exploring the relevant notions of map regularity.

Boundedness and surjectivity in normed spaces [PDF]
International Journal of Mathematics and Mathematical Sciences, 2002 We define the (w* -) boundedness property and the (w* -) surjectivity property for sets in normed spaces. We show that these properties are pairwise equivalent in complete normed spaces by characterizing them in terms of a category-like property called ...

Post-surjectivity and balancedness of cellular automata over groups [PDF]
Discrete Mathematics & Theoretical Computer Science, 2017 We discuss cellular automata over arbitrary finitely generated groups. We call a cellular automaton post-surjective if for any pair of asymptotic configurations, every pre-image of one is asymptotic to a pre-image of the other.

Surjectively rigid chains [PDF]
Mathematical Logic Quarterly, 2020 AbstractWe study rigidity properties of linearly ordered sets (chains) under automorphisms, embeddings, epimorphisms, and endomorphisms. We focus on two main cases: dense subchains of the real numbers, and uncountable dense chains of higher regular cardinalities.

Multilinear polynomials are surjective on algebras with surjective inner derivations [PDF]
Journal of Algebra, 2021 Let $f(X_1,\dots, X_n)$ be a nonzero multilinear noncommutative polynomial. If $A$ is a unital algebra with a surjective inner derivation, then every element in $A$ can be written as $f(a_1,\dots,a_n)$ for some $a_i\in A$.

Math. 151, 47--52 (1996; Zbl 0860.54028)], \textit{M.~Levin} proved that the set of all Bing maps of a compact metric space to the unit interval is a dense \(G_\delta\)-subset of the space of all maps.

Smooth Surjections Without Surjective Restrictions
Journal of Geometric Analysis, 2012 Let f : E -> F be a surjective mapping between two real or complex Banach spaces, with f having some strong differentiability properties. We investigate when there is a smaller Banach space G subset of E such that the restriction of f to G remains surjective.
