Lessons Introductory to the Modern Higher Algebra (Classic Reprint) - Softcover

Inhaltsangabe

Dive into the building blocks of higher algebra, from invariants to covariants, and see how quadrics come alive in theory and calculation.

This edition surveys the theory of quadrics in general, invariants and covariants, and the differential equations that govern them. It presents methods for testing reality of roots, forming invariants, and understanding how Hessians and related constructs fit into the broader algebraic landscape. The discussion weaves historical insight with practical symbolic techniques, aiming to illuminate how these ideas connect across topics in advanced algebra.

Readers will encounter concrete procedures for forming and manipulating quadratic and higher-order forms, along with guidance on how to apply differential equations to invariants and covariants. The material emphasizes the signs of leading terms, sum-of-squares decompositions, and the structural relationships between related expressions, all within a rigorous, step-by-step framework.

• Understanding Sturm’s related tests and how they indicate the reality of roots.


• Learning how invariants and covariants are constructed and constrained by differential relations.


• Seeing how Hessians and their iterations contribute to the study of quadratic and higher forms.


• Working through examples that connect theory to explicit symbolic calculations.

Ideal for readers of advanced algebra and those exploring the historical development of invariant theory and quadrics.
