Orthogonalization Process by Recurrence Relations

Abstract: An orthogonalization process is proposed, applicable to spaces which are realizations of abstract Hilbert space. It is simpler than the Gram-Schmidt process. A recurrence relation which orthogonalizes a physical space is proposed and it is shown that the generalized Langevin equation is contained therein. This process serves as a basis for understanding the nature of the dynamic many-body formalism.

“…O MRR utiliza o processo Grarn-Schmidt de ortogonalização, o qualé bastante geral e permite a construção de um conjunto completo de vetores ortogonalizados do espaço de Hilbert. O método de relações de recorrência foi formulado por Howard Lee [8,9], como uma generalização do formalismo desenvolvido, dentre outros, por Mori [10,11]. …”
