Topologically Transitive and Mixing Properties of Set-Valued Dynamical Systems
Abstract and Applied Analysis, 2021 We introduce and study two properties of dynamical systems: topologically transitive and topologically mixing under the set-valued setting. We prove some implications of these two properties for set-valued functions and generalize some results from a ...

Uniqueness in Rough Almost Complex Structures and Differential Inequalities [PDF]
, 2009 We prove that for almost complex structures of H\"older class at least 1/2, any J-holomorphic disc, that is constant on some non empty open set, is constant. This is in striking contrast with well known, trivial, non-uniqueness results.

Spaces of Set-Valued Functions [PDF]
Transactions of the American Mathematical Society, 1972 If X X and Y Y are topological spaces, the set of all continuous functions from X X into C Y CY , the space of nonempty, compact subsets of Y Y with the finite topology, contains a copy (with singleton sets substituted for points) of

Set-Valued Additive Functional Equations
Constructive Mathematical Analysis, 2019 In this paper, we introduce set-valued additive functional equations and prove the Hyers-Ulam stability of the set-valued additive functional equations by using the fixed point method.

Polynomial set-valued functions [PDF]
Annales Polonici Mathematici, 1996 The author gives the notion of a polynomial set-valued function for a multifunction defined on a cone and having its values in the collection of convex compact subsets of a topological vector space. The criterion for a multifunction to be a polynomial set-valued function of order at most 2 is proved.

Dedekind order completion of C(X) by Hausdorff continuous functions [PDF]
, 2004 The concept of Hausdorff continuous interval valued functions, developed within the theory of Hausdorff approximations and originaly defined for interval valued functions of one real variable is extended to interval valued functions defined on a ...

Fixed points of set-valued mappings satisfying a Banach orbital condition
Cubo, 2023 In this note, we prove a fixed point existence theorem for set-valued functions by extending the usual Banach orbital condition concept for single valued mappings.

Asymptotically Efficient Estimation of Weighted Average Derivatives with an Interval Censored Variable [PDF]
, 2013 This paper studies the identification and estimation of weighted average derivatives of conditional location functionals including conditional mean and conditional quantiles in settings where either the outcome variable or a regressor is interval-valued.

Bumping algorithm for set-valued shifted tableaux [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 We present an insertion algorithm of Robinson–Schensted type that applies to set-valued shifted Young tableaux. Our algorithm is a generalization of both set-valued non-shifted tableaux by Buch and non set-valued shifted tableaux by Worley and Sagan.

On Lipschitzian operators of substitution generated by set-valued functions [PDF]
Opuscula Mathematica, 2007 We consider the Nemytskii operator, i.e., the operator of substitution, defined by \((N \phi)(x):=G(x,\phi(x))\), where \(G\) is a given multifunction. It is shown that if \(N\) maps a Hölder space \(H_{\alpha}\) into \(H_{\beta}\) and \(N\) fulfils the ...
