In particular, P.K. Lin's norm in ℓ₁[14] and the norm v_p(•) (with p = (p_n) and lim_n p_n = 1) introduced in [3] are examples of near-infinity concentrated norms. When v_p(•) is equivalent to the ℓ₁-norm, it was an open problem as to whether (ℓ₁, v_p(•)) had the FPP. We prove that the norm v_p(•) always generates a nonreflexive Banach space X= ℝ ⊕_p₁ (ℝ ⊕_p₂ (ℝ ⊕_p₃...)) satisfying the FPP, regardless of whether v_p(•) is equivalent to the ℓ₁-norm. We also obtain some stability results.]]> Tue 23 Jun 2020 12:15:42 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23417 * have the weak fixed point property. We also prove that a uniformly Gateaux differentiable Banach space has property (⋃Ã₂) and that if X^* has property (⋃Ã₂), then X has the image-property. Criteria in order that Orlicz spaces have the properties (⋃Ã₂), (⋃Ã₂)^* and (NUS^*) are given.]]> Sat 24 Mar 2018 07:13:54 AEDT ]]>
