However, reduction to Smith normal form, named after its originator H.J.S.Smith in 1861, is a matrix version of the Euclidean algorithm and is exactly what the theory requires in both cases.? Starting with matrices over the integers, Part?1 of this book provides a measured introduction to such groups: two finitely generated abelian groups are isomorphic if and only if their invariant factor sequences are identical.? The analogous theory of matrix similarity over a field is then developed in Part?2 starting with matrices having polynomial entries: two matrices over a field are similar if and only if their rational canonical forms are equal.? Under certain conditions each matrix is similar to a diagonal or nearly diagonal matrix, namely its Jordan form..?.The reader is assumed to be familiar with the elementary properties of rings and fields.? Also a knowledge of abstract linear algebra including vector spaces, linear mappings, matrices, bases and dimension is essential, although much of the theory is covered in the text but from a more general standpoint: the role of | | 出版日期 | Textbook 2012 | | 關(guān)鍵詞 | Abelian groups; Smith normal form; equivalent matrices; homomorphisms and isomorphisms; invariant factor | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4471-2730-7 | | isbn_softcover | 978-1-4471-2729-1 | | isbn_ebook | 978-1-4471-2730-7Series ISSN 1615-2085 Series E-ISSN 2197-4144 | | issn_series | 1615-2085 | | copyright | Springer-Verlag London Limited 2012 |
