  • A simple proof of the chaoticity of shift map under a new definition of
           chaos
    • Abstract: Abstract Recently, Du has given a new strong definition of chaos by using the shift map. In this paper, we give a proof of the main theorem by constructing a dense uncountable invariant subset of the symbol space Σ2 containing transitive points in a simpler way with the help of a different metric. We also provide two examples, which support this new definition.

  • The boundedness of Toeplitz-type Operators on vanishing-morrey spaces
    • Abstract: Abstract In this note, we prove that the Toeplitz-type Operator Θ α b generated by the generalized fractional integral, Calderón-Zygmund operator and VMO funtion is bounded from L p,λ (R n ) to L q,µ(R n ). We also show that under some conditions Θ α b f ∈ VL q, µ(B R ), the vanishing-Morrey space.

  • Almost homomorphisms between unital        class="a-plus-plus">C*-algebras: A fixed point
           approach
    • Abstract: Abstract Let A,B be two unital C*-algebras. By using fixed pint methods, we prove that every almost unital almost linear mapping h: A → B which satisfies h(2 n uy)= h(2 n u)h(y) for all u ∈ U(A), all y ∈ A, and all n=0,1,2, …, is a homomorphism. Also, we establish the generalized Hyers-Ulam-Rassias stability of *-homomorphisms on unital C*-algebras.

  • Some integral inequalities for the polar derivative of a polynomial
    • Abstract: Abstract If P(z) is a polynomial of degree n which does not vanish in z < 1, then it is recently proved by Rather [Jour. Ineq. Pure and Appl. Math., 9 (2008), Issue 4, Art. 103] that for every γ> 0 and every real or complex number α with α ≥ 1, $\begin{gathered} \left\{ {\int_0^{2\pi } {\left {D_\alpha P(e^{i\theta } )} \right ^\gamma d\theta } } \right\}^{{1 \mathord{\left/ {\vphantom {1 \gamma }} \right. \kern-\nulldelimiterspace} \gamma }} \leqslant n( \alpha + 1)C_\gamma \left\{ {\int_0^{2\pi } {\left {P(e^{i\theta } )} \right ^\gamma d\theta } } \right\}^{{1 \mathord{\left/ {\vphantom {1 \gamma }} \right. \kern-\nulldelimiterspace} \gamma }} , \hfill \\ C_\gamma \left\{ {\frac{1} {{2\pi }}\int_0^{2\pi } {\left {1 + e^{i\beta } } \right ^\gamma d\beta } } \right\}^{ - {1 \mathord{\left/ {\vphantom {1 \gamma }} \right. \kern-\nulldelimiterspace} \gamma }} \hfill \\ \end{gathered} $ where D α P(z) denotes the polar derivative of P(z) with respect to α. In this paper we prove a result which not only provides a refinement of the above inequality but also gives a result of Aziz and Dawood [J. Approx. Theory, 54 (1988), 306–313] as a special case.

  • On double sine and cosine transforms, Lipschitz and Zygmund classes
    • Abstract: Abstract We consider complex-valued functions f ∈ L 1(R + 2 ), where R +:= [0,∞), and prove sufficient conditions under which the double sine Fourier transform $\hat f_{ss} $ and the double cosine Fourier transform $\hat f_{cc} $ belong to one of the two-dimensional Lipschitz classes Lip(α, β) for some 0 < α, β ≤ 1; or to one of the Zygmund classes Zyg(α, β) for some 0 < α, β ≤ 2. These sufficient conditions are best possible in the sense that they are also necessary for nonnegative-valued functions f ∈ L 1(R + 2 ).

  • Measures of weak noncompactness and fixed point theory for 1-set weakly
           contractive operators on unbounded domains
    • Abstract: Abstract The main purpose of this paper is to prove a collection of new fixed point theorems and existence theorems for the nonlinear operator equation F(x) =αx (α ≥ 1) for so-called 1-set weakly contractive operators on unbounded domains in Banach spaces. We also introduce the concept of weakly semi-closed operator at the origin and obtain a series of new fixed point theorems and the existence theorems for the nonlinear operator equation F(x) = αx (α ≥ 1) for such class of operators. As consequences, the main results generalize and improve the relevant results, which are obtained by O’Regan and A. Ben Amar and M. Mnif in 1998 and 2009 respectively. In addition, we get the famous fixed point theorems of Leray-Schauder, Altman, Petryshyn and Rothe type in the case of weakly sequentially continuous, 1-set weakly contractive (µ-nonexpansive) and weakly semi-closed operators at the origin and their generalizations. The main condition in our results is formulated in terms of axiomatic measures of weak compactness.

  • Uniform meyer solution to the three dimensional cauchy problem for laplace
           equation
    • Abstract: Abstract We consider the three dimensional Cauchy problem for the Laplace equation $\left\{ \begin{gathered} u_{xx} (x,y,z) + u_{yy} (x,y,z) + u_{zz} (x,y,z) = 0,x \in R,y \in R,0 < z \leqslant 1, \hfill \\ u(x,y,0) = g(x,y),x \in R,y \in R, \hfill \\ u_z (x,y,0) = 0,x \in R,y \in R, \hfill \\ \end{gathered} \right. $ where the data is given at z = 0 and a solution is sought in the region x,y ∈ R,0 < z < 1. The problem is ill-posed, the solution (if it exists) doesn’t depend continuously on the initial data. Using Galerkin method and Meyer wavelets, we get the uniform stable wavelet approximate solution. Furthermore, we shall give a recipe for choosing the coarse level resolution.

  • Some applications of BP-theorem in approximation theory

    -boundedness of Riesz transforms and        class="a-plus-plus">θ -Calderón-Zygmund
           operators through molecular characterization
    • Abstract: Abstract Let 0 < p ≤ 1 and w in the Muckenhoupt class A 1. Recently, by using the weighted atomic decomposition and molecular characterization, Lee, Lin and Yang[11] established that the Riesz transforms R j , j = 1,2, …,n, are bounded on H w p (R n ). In this note we extend this to the general case of weight w in the Muckenhoupt class A ∞ through molecular characterization. One difficulty, which has not been taken care in [11], consists in passing from atoms to all functions in H w p (R n ). Furthermore, the H w p -boundedness of θ-Calderón-Zygmund operators are also given through molecular characterization and atomic decomposition.

  • Bmo boundedness for banach space valued singular integrals
    • Abstract: Abstract In this paper, we consider a class of Banach space valued singular integrals. The L p boundedness of these operators has already been obtained. We shall discuss their boundedness from BMO to BMO. As applications, we get BMO boundedness for the classic g-function and the Marcinkiewicz integral. Some known results are improved.

  • Hybrid fixed point result for lipschitz homomorphisms on quasi-Banach

Also, we shall give some new results in this way and finally, give a result about hybrid fixed point of two homomorphisms on quasi-Banach algebras.
