In linear algebra, the Frobenius normal form or rational canonical form of a square matrix A with entries in a field F is a canonical form for matrices obtained by conjugation by invertible matrices over F. The form reflects a minimal decomposition of the vector space into subspaces that are cyclic for A (i.e., spanned by some vector and its repeated images under A). Since only one normal form can be reached from a given matrix (whence the "canonical"), a matrix B is similar to A if and onl… When p = q = 2 for the , norm, it is called the Frobenius norm or the Hilbert–Schmidt norm, though the latter term is used more frequently in the context of operators on (possibly infinite-dimensional) Hilbert space. This norm can be defined in various ways: ... This is true because the vector space has the finite … See more In mathematics, a matrix norm is a vector norm in a vector space whose elements (vectors) are matrices (of given dimensions). See more These norms treat an $${\displaystyle m\times n}$$ matrix as a vector of size $${\displaystyle m\cdot n}$$, and use one of the familiar … See more A matrix norm $${\displaystyle \ \cdot \ }$$ is called monotone if it is monotonic with respect to the Loewner order. Thus, a matrix norm is … See more For any two matrix norms $${\displaystyle \ \cdot \ _{\alpha }}$$ and $${\displaystyle \ \cdot \ _{\beta }}$$, we have that: for some positive … See more Suppose a vector norm $${\displaystyle \ \cdot \ _{\alpha }}$$ on $${\displaystyle K^{n}}$$ and a vector norm $${\displaystyle \ \cdot \ _{\beta }}$$ See more The Schatten p-norms arise when applying the p-norm to the vector of singular values of a matrix. If the singular values of the $${\displaystyle m\times n}$$ matrix See more Another source of inspiration for matrix norms arises from considering a matrix as the adjacency matrix of a weighted, directed graph. The so-called "cut norm" measures how close the … See more

WebJan 14, 2024 · The major goal of this work is to demonstrate that finite difference schemes exist such that they are dynamically consistent with the major features of the experimental data. Both exact and NSFD schemes are formulated and their numerics are investigated, including a detailed comparison of their corresponding numerical solutions.
