• Article: Hypercyclic behaviour of multiples of composition operators on the weighted Banach space
[Hide abstract]
ABSTRACT: Let $S(\mathbb{D})$ be the collection of all the holomorphic self-maps of open unit disk $\mathbb{D}$ of the complex plane $\mathbb{C}$, and $C_{\varphi}$, the composition operator induced by $\varphi\in S(\mathbb{D})$. For $\alpha>0,\;\lambda\in \mathbb{C}$, we give some sufficient and necessary conditions for the hypercyclicity of multiples of composition operators $\lambda C_\varphi$ acting on the weighted Banach spaces of entire functions $H_{\alpha,0}^\infty$. Moreover, we obtain a partial characterization for the frequent hypercyclicity of $\lambda C_\varphi$ on $H_{\alpha,0}^\infty$.

Article: Adjoint groups of $p$-nil rings and $p$-group automorphisms
[Hide abstract]
ABSTRACT: We introduce a class of rings, namely the class of left or right $p$-nil rings, for which the adjoint groups behave regularly. Every $p$-ring is close to being left or right $p$-nil in the sense that it contains a large ideal belonging to this class. Also their adjoint groups occur naturally as groups of automorphisms of $p$-groups. These facts and some of their applications are investigated in this paper.

• Article: The sign of wreath product representations of finite groups
[Hide abstract]
ABSTRACT: Introduction: Let G, H be finite groups. T. Müller [Adv. Math. 153, No. 1, 118-154 (2000; Zbl 1004.20016)] developed an enumerative theory of homomorphisms φ:G→H≀S n , as n→∞, and asked to generalize this theory to other sequences of groups. In particular, he conjectured the following. Conjecture 1. Let G, H be a finite groups. Then we have for n→∞ |Hom(G,H≀A n )|=1 1+s 2 (G) + O (e -cn 1/|G| )|Hom(G,H≀S n )|, where s 2 (G) is the number of subgroups of index 2 in G. It is the aim of this note to proof this conjecture. Theorem 1. Conjecture 1 holds true for all finite groups G and H.

• Article: Generalized Köthe p-dual spaces
[Hide abstract]
ABSTRACT: Let us consider a Banach function space X. The Köthe dual space can be characterized as the space of multipliers from X to L1. We extend this characterization to the space of multipliers from X to Lp in order to de�ne the Köthe p-dual space of X. We analyze the properties of this space so as to use it as a tool for studying p-th power factorable operators. In particular, we compute q-concavity for these spaces and type and cotype when X is an AM-space. As main applications, we give a characterization for Hilbert Banach function spaces, as well as a factorization for p-th power factorable operators through an L(p,1)-space.

• Article: Functional differential inequalities with partial derivatives
[Hide abstract]
ABSTRACT: Initial problems for Hamilton-Jacobi functional differential equations and initial boundary value problems of Dirichlet type for parabolic equations are considered. It is proved that classical solutions of functional differential equations can be estimated by solutions of initial problems for ordinary functional differential equations. Theorems on the uniqueness of solutions are obtained as consequences of comparison results. A method of differential inequalities is used. Here, the involved operators do not satisfy the Volterra condition.
