Summary
[edit]DescriptionApprossimazione di una involuzione solida.jpg |
Italiano: Involuzione approssimata
في الحالة التي تكون فيها كل نقطة من سطح يقابلها نقطة واحدة فقط من نفس السطح ، يكون هناك علاقة التفافية على السطح نفسه Invece nel caso in cui la superficie K sia una quadrica e V sia un punto non appartenente a K. L'insieme delle proiezioni dei punti P di K dal punto V su K è rappresentato da un’altra quadrica k' che coincide con K. L'asserzione che K′ coincide con K può essere scritta cosi: k' = {k ∩ (PV) ∣ P ∈ K} Dove: - K′ rappresenta l'insieme delle proiezioni dei punti di K dal punto V su K, - (PV) rappresenta la stella di rette che passa per il centro di proiezione V e per ciascun punto P ∈ K, - k’ ∩ (PV) è l'intersezione tra k’ e la stella di rette per V e P, - P ∈ K significa che P è un punto sulla quadrica K. Poiché per ogni punto P di K, corrisponde un solo punto P' di k’, per cui si ha una involuzione solida tra due quadriche coincidenti k e k’ approssimazione di una involuzione solida approximation of a solid involution https://www.researchgate.net/profile/Hasan-Isawi/research |
