Power transformer design normally includes an optimization process which involves the assessment of a great number of design alternatives. This calculation process normally requires a high computation time and its reduction ...

In this paper we introduce a conjugate class of Riesz transforms in the context of Laguerre polynomials. We prove their weak-type (1,1) and Lp, 1

We obtain sharp power-weighted L p , weak type and restricted weak type inequalities for the heat and Poisson integral maximal operators, Riesz transform and a Littlewood-Paley type square function, emerging naturally in ...

The Human Resources (HR) outsourcing market in Peru is growing; however, it is dominated by large companies in this area, which prevents the development of new organizations or small- and medium-sized enterprises (SMEs). ...

Let λ∈ (0,1) and let T be a r x r complex matrix with polar decomposition T=U|T|. Then, the λ- Aluthge transform is defined by Δλ(T)= |T|λU |T |1-λ. Let Δnλ(T) denote the n-times iterated Aluthge transform of T, n ∈ N. We ...

We extend the results by Jones and Rosenblatt about the series of the differences of differentiation operators along lacunary sequences to BMO and to the setting of weighted Lp spaces. We use a different approach which ...
