in recent years, degradation of environment (water and soil resources) by farmers has increase concerns about sustainability of agriculture. farmers’ behaviors affect conservation of these resources and play important role in sustainability of agriculture as well. shiraz county, like other parts of the country, suffers for degradation of soil and water resources. the aim of this study was to pr...

In this paper, we introduce the local and global mixed Morrey-type spaces show some properties. Besides, investigate boundedness of fractional integral operators $$I_\alpha $$ in these spaces. Firstly, sufficient necessary conditions mixed-norm Lebesgue for Then, prove $$I_{\alpha }$$ by Hardy operators’ weighted Furthermore, obtain corollaries.

In this paper, we show that the Bergman functions on Siegel upper half-space enjoy following uniqueness property: if f ∈...

Abstract We prove that if G is a discrete group and $$(A,G,\alpha )$$ ( A , G α ) C*-dynamical system such the reduced crossed product $$A\rtimes _{r,\alpha } G$$ ⋊ r...

We study the double bubble problem with perimeter taken respect to $$\ell _1$$ norm on $${{\mathbb {R}}}^2$$ . give an elementary proof for existence of minimizing sets any volume ratio parameter $$0<\alpha \le 1$$ by direct comparison a small family parameterized sets. By simple analysis this family, we obtain shapes found in Morgan et al. J Geom Anal 8(1):97-*115 , 1998.

This paper studies certain inverse problems in the optimal frequency-domain synthesis of robust controllers, in both the 2-norm and the infinity-norm. These inverse problems identify the class of controllers which are optimal for some choice of weights. Their implications for loopshaping are discussed.

Let $\mathcal{X}$ be a separable Hilbert space with norm $\|\cdot\|$ and let $T>0$. $Q$ linear, self-adjoint, positive, trace class operator on $\mathcal{X}$, $F:\mathcal{X}\rightarrow \mathcal{X}$ (smooth enough) function $W(t)$ $\mathcal{X}$-valued cylindrical Wiener process. For $\alpha\in [0,1/2]$ we consider the $A:=-(1/2)Q^{2\alpha-1}:Q^{1-2\alpha}(\mathcal{X})\subseteq \mathcal{X}\righta...
