The Tsirelson space
Ο χώρος του Τσίρελσον

Μυργιώτης, Απόστολος Παναγιώτη

The Tsirelson space consists of sequences, has infinite dimwnsions, is Banach and reflexive. Also, is proved that (Co, || ||∞) and (lp, || ||p), ∀p∈[1, +∞) are not contained isomorphically in Tsirelson space. The last property makes Tsirelson space important because answers negatively in a conjecture in area of Functional Analysis: "Every infinite-dimension and reflexive Banach space contains isomorphically (Co, || ||∞) or (lp, || ||p), for p∈[1, +∞)
Ο χώρος του Tsirelson είναι ένας χώρος ακολουθιών, απειροδιάστατος, Banach και αυτοπαθής. Στην εργασία αποδεικνύονται οι παραπάνω ιδιότητες καθώς και το ότι οι χώροι (Co, || ||∞) και (lp, || ||p),∀p∈[1, +∞) δεν εμφυτεύονται ισομορφικά σ' αυτόν. Η τελευταία ιδιότητα τον καθιστά αξιόλογο, επειδή με την κατασκευή του απαντήθηκε αρνητικά μια εικασία στο χώρο της Συναρτησιακής Ανάλυσης : "Κάθε απειροδιάστατος αυτοπαθής χώρος Banach περιέχει ισομορφικά τον Co ή κάποιον lp, p∈[1, +∞).
