Homothetic vector field : ウィキペディア英語版 | Homothetic vector field A homothetic vector field (sometimes homothetic collineation or homothety) is a projective vector field which satisfies the condition: : where c is a real constant. Homothetic vector fields find application in the study of singularities in general relativity. They can also be used to generate new solutions for Einstein equations by similarity reduction. ==See also==
