In this article we construct affine systems that provide a simultaneous atomic decomposition for a wide class of functional spaces including the Lebesgue spaces Lp(Rd) 1 < p < +∞. The novelty and difficulty of this construction ...

We solve the Bjorling problem for timelike surfaces in the Lorentz-Minkowski space through a split-complex representation formula obtained for this kind of surface. Our approach uses the split-complex numbers and natural ...

Given α > 0 and a space of homogeneous type X, n-normal, with n ℝ+, we consider an extension of the standard multilinear fractional integral on Lp1 × ... × Lpk for the range of 1/pi = 1/p1...+1/pk -α/n ≤ 0. We show that ...

Monitoring urban green space (UGS) indicators is key to assessing progress against the UNs sustainable devel-opment goals (SDGs). Within these indicators, measuring the provision of UGS as well as its accessibility is ...

In this chapter, several systems engineering tools are presented and analyzed to determine shortcomings of these tools to improve the efficiency and efficacy of them working together in a modified design thinking methodology ...

En esta práctica, se debe tener en cuenta; el impacto, innovación y aceptación del negocio en el que está la empresa para un aceptación más amplia en el mercado, generando nuevas estrategias y control de su propio ...

The demands for improvement in sound quality and reduction of noise generated by vehicles are constantly increasing, as well as the penalties for space and weight of the control solutions. A promising approach to cope with ...

We show decay bounds of the form ∫Rd ϕ(u(x,t))dx≤Ct-μ for integrable and bounded solutions to the nonlocal evolution equation ut(x,t)= ∫Rd J(x,y)G(u(y,t)-u(x,t))(u(y,t)-u(x,t))dy+f(u(x,t)). Here G is a nonnegative and even ...
