Sums of Powers and Majorization [PDF]
We study certain sequences involving sums of powers of positive integers and in connection with this, we give examples to show that power majorization does not imply ...

A-Browder-type theorems for direct sums of operators [PDF]
We study the stability of a-Browder-type theorems for orthogonal direct sums of operators. We give counterexamples which show that in general the properties $(\rm SBaw)$, $(\rm SBab)$, $(\rm SBw)$ and $(\rm SBb)$ are not preserved under direct sums of ...

Partially Coherent Direct Sum Channels [PDF]
We introduce Partially Coherent Direct Sum (PCDS) quantum channels, as a generalization of the already known Direct Sum quantum channels. We derive necessary and sufficient conditions to identify the subset of those maps which are degradable, and provide a simplified expression for their quantum capacities.

Summary: The \textit{\(k\)-fold direct sum encoding} of a string \(a\in\{0,1\}^n\) is a function \(f_a\) that takes as input sets \(S\subseteq [n]\) of size \(k\) and outputs \(f_a(S)=\sum_{i\in S}a_i\pmod 2\). In this paper we prove a direct sum testing theorem. We describe a three query test that accepts with probability one any function of the form \

The presence of cloud cover usually reduces incoming solar radiation. The influence of cloudiness on solar energy reaching Earth’s surface mostly depends on the cloud amount, its genera and other properties. Due to processes of absorption, scattering and

$k$-bitransitive and compound operators on Banach spaces
In this this paper, we introduce new classes of operators in complex Banach spaces, which we call $k$-bitransitive operators and compound operators to study the direct sum of diskcyclic operators.

From Oscillatory Integrals and Sublevel Sets to Polynomial Congruences and Character Sums [PDF]
We present a slight extension of a classical lemma of Hensel and give various applications to polynomial congruences and character sums; in particular, we give a new proof of a classical result of Hua on complete exponential sums.
