In this note we announce our investigation on the Lp properties for periodic and discrete multilinear pseudo-differential operators. First, we review the periodic analysis of multilinear pseudo-differential operators by showing classical multilinear

APPLICABLE ANALYSIS
In this paper, we study some operator theoretical properties of pseudo-differential operators with operator-valued symbols on the Heisenberg motion group. Specifically, we investigate L-2-L-p boundedness of pseudo-differential operators on the Heisen

In this paper, for a locally compact commutative hypergroup K K and for a pair ( Φ 1 , Φ 2 ) (\Phi _1, \Phi _2) of Young functions satisfying sequence condition, we give a necessary condition in terms of aperiodic elements of the center of K , K, f

Given a compact (Hausdorff) group $G$ and a closed subgroup $H$ of $G,$ in this paper we present symbolic criteria for pseudo-differential operators on compact homogeneous space $G/H$ characterizing the Schatten-von Neumann classes $S_r(L^2(G/H))$ fo

In this paper we investigate the nuclear trace of vector‐valued Fourier multipliers on the torus and its applications to the index theory of periodic pseudo‐differential operators. First we characterise the nuclearity of pseudo‐differential ope

Let $G$ be a compact Lie group. In this article, we investigate the Cauchy problem for a nonlinear wave equation with the viscoelastic damping on $G$. More preciously, we investigate some $L^2$-estimates for the solution to the homogeneous nonlinear

Let K be a commutative or compact hypergroup. Let $$\mu $$ be a bounded complex-valued Borel measure on K, and let $$T_\mu $$ be the corresponding convolution operator of $$L^1(K)$$ . Let S be a bounded linear operator on a Banach space X. We prove t

In this paper we provide sharp results for the Dixmier traceability of discrete pseudo-differential operators on $\ell^2(\mathbb{Z}^n)$. In this setting, we introduce a suitable notion of a class of classical symbols which provide a class of Dixmier
