一种描述微扰理论修正发散的方法是由Hans Kramers<ref>Kramers presented his work at the 1947 Shelter Island Conference, repeated in 1948 at the Solvay Conference. The latter did not appear in print until the Proceedings of the Solvay Conference, published in 1950 (see Laurie M. Brown (ed.), ''Renormalization: From Lorentz to Landau (and Beyond)'', Springer, 2012, p. 53). Kramers' approach was nonrelativistic(see Jagdish Mehra, Helmut Rechenberg, ''The Conceptual Completion and Extensions of Quantum Mechanics 1932-1941.

凝聚态物理学对重整化过程的物理意义和推广提供了更深入的理解，它超越了传统重整化理论的膨胀群。Leo P. Kadanoff在1966年的论文中提出了“块区自旋”重整群。<ref>[[Leo Kadanoff|L.P. Kadanoff]] (1966): "Scaling laws for Ising models near <math>T_c</math>", ''Physics (Long Island City, N.Y.)'' '''2''', 263.</ref>分块思想是一种将理论中远距离的分量定义为较短距离分量的集合的方法。
