ON NULL CURVES ON SURFACES AND NULL VECTORS IN LORENTZ SPACE

Year 2007, Volume: 2 Issue: 1, 111 - 116, 01.06.2007

Abstract

 In this work, we compare the Darboux frame and the Frenet frame of a null curve lying on a spacelike surface in the three-dimensional Lorentz space, and we show that the normal curvature of the curve is a constant. Then we study the inner product of null vectors, to have results in terms of angles.

LORENTZ UZAYINDA YÜZEYLER ÜZERİNDEKİ NULL EĞRİLER VE NULL VEKTÖRLER ÜZERİNE

Özet: Bu çalışmada, üç boyutlu Lorentz uzayında bir spacelike yüzey üzerinde yatan bir null eğrinin Darboux çatısı ile Frenet çatısı karşılaştırıldı ve normal eğriliğin sabit olduğu gösterildi. Daha sonra da null vektörlerin iç çarpımları incelendi ve açılar cinsinden sonuçlar elde edildi.
