在任意重新标度{{mvar|λ}}下，标度不变也允许曲线进行旋转；换句话说，{{math|''θ''(''λr'')}}与其旋转后的{{math|''θ''(''r'')}}一模一样。

The idea of scale invariance of a monomial generalizes in higher dimensions to the idea of a [[homogeneous polynomial]], and more generally to a [[homogeneous function]]. Homogeneous functions are the natural denizens of [[projective space]], and homogeneous polynomials are studied as [[projective varieties]] in [[projective geometry]]. Projective geometry is a particularly rich field of mathematics; in its most abstract forms, the geometry of [[scheme (mathematics)|schemes]], it has connections to various topics in [[string theory]].

单项式标度不变性的概念在高维时推广到齐次多项式，更一般地推广到齐次函数。齐次函数是射影空间的“土著”，齐次多项式在射影几何中作为射影簇进行研究。射影几何是数学中一个内容特别丰富的领域；在它最抽象的形式，方案的几何学中，它与弦理论中的各种主题都有联系。
