Boundedness for fractional Hardy-type operator on variable exponent Herz-Morrey spaces
Jiang-Long Wu, Wen-Jiao Zhao
In this paper, the fractional Hardy-type operator of variable order is shown to be bounded from the variable exponent Herz-Morrey spaces $M\dot{K}_{p_{_{1}},q_{_{1}}(\cdot)}…
Two Results on Homogeneous Hessian Nilpotent Polynomials
Arno van den Essen, Wenhua Zhao
Let and the Laplace operator. A formal power series is said to be {\it Hessian Nilpotent}(HN) if its…
A Vanishing Conjecture on Differential Operators with Constant Coefficients
Wenhua Zhao
In the recent progress [BE1], [Me] and [Z2], the well-known JC (Jacobian conjecture) ([BCW], [E]) has been reduced to a VC (vanishing conjecture) on the Laplace operators and HN (H…
Some Properties of and Open Problems on Hessian Nilpotent Polynomials
Wenhua Zhao
In the recent progress [BE1], [M], [Z1] and [Z2], the well-known Jacobian conjecture ([BCW], [E]) has been reduced to a problem on HN (Hessian nilpotent) polynomials (the polynomia…
NCS Systems over Differential Operator Algebras and the Grossman-Larson Hopf Algebras of Labeled Rooted Trees
Wenhua Zhao
Let be any unital commutative $\bQ$-algebra and any non-empty subset of $\bN^+$. Let be commutative or noncommutative free variables and a formal ce…
Noncommutative Symmetric Functions and the Inversion Problem
Wenhua Zhao
Let be any unital commutative $\bQ$-algebra and commutative or noncommutative variables. Let be a formal central parameter and $\kttzz$ the formal…
