توضیحاتی در مورد کتاب راهنمای گروه ها، حلقه ها و زمینه ها
ساختارهای جبری در ریاضیات همه جا حاضر شده اند، تقریباً همه ریاضیدانان در طول دوره تحقیقات خود با گروه ها، حلقه ها، میدان ها یا اشیاء عجیب و غریب مرتبط بیشتری روبرو می شوند. این کتاب مروری بر برخی از مهمترین ساختارهای جبری در ریاضیات مدرن با تأکید بر ایجاد تصویری منسجم از نحوه تعامل همه آنها ارائه می دهد. علاوه بر مطالب استاندارد در مورد گروه‌ها، حلقه‌ها، ماژول‌ها، میدان‌ها و نظریه گالوا، این کتاب شامل بحث‌هایی درباره موضوعات مهم دیگر، از جمله گروه‌های خطی، نمایش‌های گروهی، حلقه‌های آرتینی، مدول‌های پروژکتوری، تزریقی و مسطح، حوزه‌های Dedekind و مرکزی است. جبرهای ساده همه قضایای مهم معمولاً بدون اثبات، اما اغلب با بحث در مورد ایده‌های شهودی پشت آن اثبات‌ها مورد بحث قرار می‌گیرند. این راهنمای روشنگر هم برای دانشجویان فارغ التحصیل در رشته ریاضیات که تحصیلات خود را شروع می کنند و هم برای محققانی که مایلند تصویر بزرگتر ساختارهای جبری را که با آنها روبرو می شوند درک کنند ایده آل است.
توضیحاتی درمورد کتاب به خارجی
Algebraic structures have come to be ubiquitous in mathematics, with almost all mathematicians encountering groups, rings, fields or more exotic related objects during the course of their research. This book presents an overview of some of the most important algebraic structures in modern mathematics, with an emphasis on creating a coherent picture of how they all interact. In addition to the standard material on groups, rings, modules, fields, and Galois theory, the book includes discussions of other important topics, including linear groups, group representations, Artinian rings, projective, injective and flat modules, Dedekind domains, and central simple algebras. All of the important theorems are discussed, typically without proofs, but often with a discussion of the intuitive ideas behind those proofs. This insightful guide is ideal for both graduate students in mathematics who are beginning their studies, and researchers who wish to understand the bigger picture of the algebraic structures they encounter.
