Kutilayotgan natijalar va ularning ahamiyati: Geometriyada figura tushunchasi birinchi bo‘lib, Yunonistonda 2350 yil ilgari tariflangan edi. Ular tekislikning yoki uch o‘lchovli fazoning ixtiyoriy qism to‘plamiga figura deb tarif berishgan. Ular tekislikdagi yoki uch o‘lchovli Evklid fazosidagi figuralarning tenglik tarifini xam berganlar. Ular tekislikdagi yoki uch o‘lchovli Evklid fazosidagi uchburchaklarning, to‘rtburchaklarning va boshqa baьzibir ko‘pburchaklarning tenglik shartlarini topishgan.
1850 yildan boshlab Evropada matematikaning yangi soxasi-“invariantlar nazariyasi” nomli soxasi rivojlana boshladi. Shu vaqtga kelib, matematikada ko‘p o‘lchovli chiziqli fazolarda cheksiz ko‘p geometriyalar paydo bo‘ldi. Yangi paydo bo‘lgan xarbir geometriyada figura tushunchasi tariflanib, figuralarning tenglik tushunchasi taьrifi berildi. Invariantlar nazariyasida chekli sondagi elementli figuralarning tenglik problemasini echish bilan shug‘ullanildi.
O‘sha davrda mashhur nemis matematigi Feliks Kleyn aytgan edi: Harqanday geometriya bu geometriyaning o‘zgartirishlari gruppasinig invariantlari nazariyasidir. Invariantlar nazariyasida faqat chekli sondagi elementli figuralarning tenglik problemasini echish bilan shug‘ullanilgani uchun, u vaqtlarda geometriyalarda faqat chekli sondagi elementli figuralar bilan shug‘ullanilgan. Keyinroq geometriyalarda (masalan, differentsial geometriyada) baьzi cheksiz elementli figuralar bilan ham shug‘ullanish boshlangan.
Bizning proektda figura tushunchasi geometriyalardagi figura tushunchasiga ko‘ra ancha keng taьrifi berildi va bu figuralarning invariantlari nazariyasi rivojlantirildi. Bir L chiziqli fa’zo va ixtiyoriy bir T to‘plam berilgan bo‘lsin. T to‘plam L ning ichida bo‘lishi mumkin yoki bo‘lmasligi ham mumkin.
Bizning figuraga oit birinchi ta’rifimiz quyidagichadir: T ixtiyoriy bir to‘plam bo‘lsin. T to‘plamning L chiziqli fazoga aks ettirishiga L da parametrik figura deyiladi.
Figuraga oit ikkinchi ta’rifimiz quyidagichadir: T topologik fazo va L topologik vektor fazo bo‘lsin. T-topologik fazoning L topologik vektor fazoga uzluksiz aks ettirishiga L fazodagi parametrik topologik T-figura deyiladi.
Figuraning bashqa ta’riflari, xususan, silliq figura va polinom xususiyatli figura ta’riflarini ham berdik. Qisqalik uchun ular bu erda berimadi.
Loyihamizning asosiy maqsadlari quyidagilardan iborat:
1). T-bo‘sh bo‘lmagan bir to‘plam va L n-o‘lchovli Evklid fazosi bo‘lgan holda, parametrik figuralarning invariantlari nazariyasini rivojlantirish.
2) 1). T-bo‘sh bo‘lmagan bir topologik fazo va L n-o‘lchovli affin fazo bo‘lgan holda, parametrik topologik figuralarning invariantlari nazariyasini rivojlantirish.
3). T-bo‘sh bo‘lmagan bir topologik fazo va L n-o‘lchovli Evklid fazosi bo‘lgan holda, parametrik topologik figuralarning invariantlari nazariyasini rivojlantirish.
4) 1). T-bo‘sh bo‘lmagan bir topologik fazo va L 2-o‘lchovli psevdo-Evklid fazo bo‘lgan holda, parametrik topologik figuralarning invariantlari nazariyasini rivojlantirish.
5). T, n-o‘lchovli Evklid fazosida bir ochiq to‘plam va L n-o‘lchovli Evklid fazosi bo‘lgan holda, parametrik silliq figuralarning invariantlari nazariyasini rivojlantirish.
