Continuity of Bounded Linear Operators on Normed Linear Spaces [PDF]
Summary In this article, using the Mizar system [1], [2], we discuss the continuity of bounded linear operators on normed linear spaces. In the first section, it is discussed that bounded linear operators on normed linear spaces are uniformly continuous and Lipschitz continuous.

ON A TAUBERIAN CONDITION FOR BOUNDED LINEAR OPERATORS [PDF]
Let \(T\) be a bounded linear operator on a complex Banach space \(X\). The operator \(T\) is called power bounded if there is a constant \(C\) such that \(\| T^{n} \| \leq C\) for all \(n = 1,2,\dots\). The main results of the paper are the following. Assume that the operator \(T\) satisfies the Tauberian condition \[ \sup_{n \geq 1} (n + 1) \| (I - T)

Metatimes, random measures and cylindrical random variables
Metatimes constitute an extension of time-change to general measurable spaces, defined as mappings between two σ-algebras. Equipping the image σ-algebra of a metatime with a measure and defining the composition measure given by the metatime on the domain

Projections in the spaces of bounded linear operations [PDF]
For Banach spaces X, Z, let B(X, Z) denote the space of bounded linear operators from X into Z and K(X, Z) (resp. W(X, Z)) the subspace of compact (resp. weakly compact) operators. It is shown that (a) if X contains an isomorph of Co, then K(X, Γ) is not complemented in B(X, Γ), (b) if S is a compact Hausdorff space which is not scattered, then K(C(S),

STRUCTURED CONDITION PSEUDOSPECTRA AND STRUCTURED ESSENTIAL CONDITION PSEUDOSPECTRA OF BOUNDED LINEAR OPERATORS ON ULTRAMETRIC BANACH SPACES [PDF]
In this paper, we introduce and study the structured condition pseudospectra and the structured essential condition pseudospectra of bounded linear operators on ultrametric Banach spaces.

Linear maps preserving equivalence or asymptotic equivalence on Banach space
Let XX be a complex Banach space with dimension at least two and B(X)B\left(X) the algebra of all bounded linear operators on XX. We show that a bijective linear map Φ\Phi preserves asymptotic equivalence if and only if it preserves equivalence, and in ...

Bounded linear operators between C∗-algebras [PDF]
Let $u:A\to B$ be a bounded linear operator between two $C^*$-algebras $A,B$. The following result was proved by the second author. Theorem 0.1. There is a numerical constant $K_1$ such that for all finite sequences $x_1,\ldots, x_n$ in $A$ we have $$\leqalignno{&\max\left\{\left\|\left(\sum u(x_i)^* u(x_i)\right)^{1/2}\right\|_B, \left\|\left(\sum

The uniform boundedness principle for order bounded operators
Under appropriate hypotheses on the spaces, it is shown that a sequence of order bounded linear operators which is pointwise order bounded is uniformly order bounded on order bounded subsets.
