Ibn Turk sahifasining manbasini koʻrish

'''{{Transl|ar|ALA|ʿAbdulhamīd ibn Turk|italics=no}}''' ([[Floruit|taxm. yashagan]] 830-yillar), shuningdek '''{{Transl|ar|ALA|ʿAbdulhamīd ibn Vase ibn Turk al-Jiliy|italics=no}}''' ({{Lang-ar|ابومحمد عبدالحمید بن واسع بن ترک الجیلی}}) nomi bilan ham tanilgan, IX asr islom matematigi boʻlgan. Uning hayoti haqida yetarlicha maʼlumot mavjud emas. U haqdagi ikki yozma maʼlumot biri [[Ibn an-Nadim]], ikkinchisi [[Ibn al-Qiftiy|Al-Qiftiy]] tomonidan yozilan boʻlib, bir-biriga aynan mos kelmaydi. Al-Qiftiy uning ismini Abdulhamīd ibn Vase ibn Turk al-Jiliy deb keltiradi. Jiliy — [[Gilon ustoni|Gilon]]dan ekanini anglatadi. Boshqa tomondan, [[Ibn an-Nadim]] uning nisbasi sifatida {{Transl|ar|xuttaliy}} ({{Lang|ar|ختلی|rtl=yes}})ni keltiradi; bu hudud Amudaryoning shimolida va [[Badaxshon|Badaxshon]]ning gʻarbida joylashgan. U yozgan {{Transl|ar|al-jabr va al-muqabila}} asarining bizgacha yetib kelgan ikki qoʻlyozmasidan birida nisbaning yozilishi {{Transl|ar|al-Jiliy}} shakliga yaqin<ref name="cgie">[http://www.cgie.org.ir/fa/publication/entryview/1465 Ibn Turk] in ''Dāʾirat al-Maʿārif-i Buzurg-i Islāmī'', Vol. 3, no. 1001, Tehran. To be translated in [[Encyclopaedia Islamica]].</ref>. [[David Pingree]] / ''[[Encyclopaedia Iranica]]''da u aslida Xuttal yoki [[Gilon ustoni|Gilon]]dan boʻlganini qayd etiladi{{Sfn|Pingree|1982|page=111}}.

Ibn Turk ''Aralash tenglamalardagi mantiqiy zaruriyatlar'' nomli [[Algebra|algebra]] asarini yozgan boʻlib, u Al-Xorazmiyning {{Transl|ar|Al-Jabr}} asariga juda oʻxshash va taxminan oʻsha davrda, hatto ehtimol undan ham avvalroq nashr etilgan<ref name="Boyer Ibn Turk">{{cite book|first=Carl B.|last=Boyer|authorlink=Carl Benjamin Boyer|title=A History of Mathematics|edition=Second|publisher=[[John Wiley & Sons, Inc.]]|year=1991|chapter=The Arabic Hegemony|isbn=0-471-54397-7|quote=The ''Algebra'' of [[Al-Khwarizmi]] usually is regarded as the first work on the subject, but a recent publication in Turkey raises some questions about this. A manuscript of a work by 'Abd-al-Hamid ibn-Turk, entitled "Logical Necessities in Mixed Equations", was part of a book on {{translit|ar|Al-jabr wa'l muqabalah}} which was evidently very much the same as that by Al-Khwarizmi and was published at about the same time — possibly even earlier. The surviving chapters on „Logical Necessities“ give precisely the same type of geometric demonstration as al-Khwarizmi’s ''Algebra'' and in one case the same illustrative example x<sup>2</sup> + 21 = 10x. In one respect, 'Abd-al-Hamad’s exposition is more thorough than that of al-Khwarizmi, for he gives geometric figures to prove that if the discriminant is negative, a quadratic equation has no solution. Similarities in the works of the two men and the systematic organization found in them seem to indicate that algebra in their day was not so recent a development as has usually been assumed. When textbooks with a conventional and well-ordered exposition appear simultaneously, a subject is likely to be considerably beyond the formative stage. … Note the omission of [[Diophantus]] and [[Pappus of Alexandria|Pappus]], authors who evidently were not at first known in Arabia, although the Diophantine ''Arithmetica'' became familiar before the end of the tenth century.|page=[https://archive.org/details/historyofmathema00boye/page/234 234]|chapter-url-access=registration|chapter-url=https://archive.org/details/historyofmathema00boye/page/234}}</ref>. Faqat ''Aralash tenglamalardagi mantiqiy zaruriyatlar'' deb ataluvchi, [[Kvadrat tenglama|kvadrat tenglamalar]]ni yechishga bagʻishlangan bir bobigina bizgacha yetib kelgan. Qoʻlyozmada {{Transl|ar|Al-Jabr}}da keltirilgan bilan aynan bir xil geometrik isbot, hatto bir holatda {{Transl|ar|Al-Jabr}}dagi bilan bir xil misol beriladi va hatto {{Transl|ar|Al-Jabr}}dan ham oshib, agar [[Diskriminant|diskriminant]] manfiy boʻlsa, kvadrat tenglama yechimga ega boʻlmasligini geometrik yoʻl bilan isbotlanadi<ref name="Boyer Ibn Turk" />. Ushbu ikki asar oʻrtasidagi oʻxshashlik baʼzi tarixchilarga Al-Xorazmiy va Abdulhamid davriga kelib algebra allaqachon yaxshi rivojlangan boʻlgan, degan xulosaga kelishlariga sabab boʻlgan<ref name="Boyer Ibn Turk" />.
