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, also it can be used to generate new solutions for Einstein equations by similarity reduction.[1]
