Convolution in Dual Cesàro Sequence Spaces [PDF]
, 2022 We investigate convolution operators in the sequence spaces $d_p$, for 1 $\leqslant p 1, arise as dual spaces of the Cesàro sequence spaces $ces_p$ thoroughly investigated by G. Bennett.

On manimax theory in two Hilbert spaces
International Journal of Mathematics and Mathematical Sciences, 1996 In this paper, we investigated the minimax of the bifunction J:H1(Ω)xV2→RmxRn, such that J(v1,v2)=((12a(v1,v1)−L(v1)),v2) where a(.,.) is a finite symmetric bilinear bicontinuous, coercive form on H1(Ω) and L belongs to the dual of H1(Ω).

A Study of Spaces of Sequences in Fuzzy Normed Spaces
Mathematics, 2021 In this paper, spaces of sequences in fuzzy normed spaces are considered. These spaces are a new concept in fuzzy normed spaces. We develop fuzzy norms for spaces of sequences in fuzzy normed spaces. Especially, we study the representation of the dual of

Continuous $k$-Fusion Frames in Hilbert Spaces [PDF]
Sahand Communications in Mathematical Analysis, 2020 The study of the c$k$-fusions frames shows that the emphasis on the measure spaces introduces a new idea, although some similar properties with the discrete case are raised. Moreover, due to the nature of measure spaces, we have to use new techniques for

A Study of Approximation Properties in Felbin-Fuzzy Normed Spaces
Mathematics, 2020 In this paper, approximation properties in Felbin-fuzzy normed spaces are studied. These approximation properties have been recently introduced in Felbin-fuzzy normed spaces. We make topological tools to analyze such approximation properties.

Dual polar spaces of arbitrary rank [PDF]
, 2011 In 1982 P. Cameron gave a characterisation of dual polar spaces of finite rank viewed as point-line spaces. This characterisation makes essential use of the fact that dual polar spaces of finite rank have finite diameter.
