Krein-Rutman Theorem and the Principal Eigenvalue

In this chapter, we rst recall the well-known Krein-Rutman theorem and then combine it with the classical maximum principle of elliptic operators to prove the existence of principle eigenvalues for such operators.

Krein–Rutman theorem - Wikipedia

In functional analysis, the Krein–Rutman theorem is a generalisation of the Perron–Frobenius theorem to infinite-dimensional Banach spaces. [1] It was proved by Krein and Rutman in 1948.

怎样理解krien Rutman定理和相应的椭圆算子的特征值问题?

而Krein-Rutman定理 「不过」是把这个结果推到了无限维空间。 当然了,这个推广不是平凡的,否则也不足以被命名了。 我们需要orderd Banach space来替换原来实数空间,因为你需要定义半序。 紧算子是最接近「有限维」算子的一个算子。

克列因-鲁特曼定理_百度百科

克列因-鲁特曼定理是数学中研究非负核线性积分算子特征值问题的定理,属于无穷维有序Banach空间中正紧算子的Perron-Frobenius定理推广。 该定理用于证明椭圆算子和周期抛物问题的主特征值存在性及唯一性。

The classical Krein-Rutman theorem - MathOverflow

Jun 15, 2011 · The classical Krein-Rutman theorem states that any positive compact linear endomorphism $T:X \to X$ on a Banach space $X$ with positive spectral radius $r (T)$ has an eigenvalue $r (T)$ with a positive ...

This yields a simplified Krein-Rutman theorem in the Banach lattice of finite mea-sures for Markov operators, providing the existence of f1 whilst λ1 = 0 and φ1 = 1 are known by definition.
