We also show that for a subspace E ⊆ {(x, −x) : x ∈ R} of the Sorgenfrey plane S2 the following conditions are equivalent: (i) E is C-embedded in S2; (ii) E is C∗-embedded in S2; (iii) E is a countable Gδ -subspace of R2 and (iv) E is a countable functionally closed subspace of S2.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)C∗ -embeddedC-embeddedThe Sorgenfrey planeArtículo2015-05-1310.4995/agt.2015.3161Abierto1989-4147
