These lessons show how to maximize instruction that prepares students for formal algebra. Through a series of investigations that help students make connections between arithmetic and algebra, students build proficiency with key algebraic concepts - patterns, functions, and variables. They use multiple representations including models, drawings, tables, graphs, words, and symbols. Lessons include a technology component with suggestions for teaching with graphing calculators.
Algebraic K-theory is an important part of homological algebra. From the table of contents: Projective Modules and Vector Bundles; The Grothendieck group K_0; K_1 and K_2 of a ring; Definitions of higher K-theory; The Fundamental Theorems of higher K-theory.
Algebraic Techniques and Semidefinite Optimization
This research-oriented course will focus on algebraic and computational techniques for optimization problems involving polynomial equations and inequalities with particular emphasis on the connections with semidefinite optimization. The course will develop in a parallel fashion several algebraic and numerical approaches to polynomial systems, with a view towards methods that simultaneously incorporate both elements.
Except for a few added comments, this is a faithful translation of the book Strutture simpliciali in topologia, published by Pitagora Editrice, Bologna 2009, as part of the collection Quaderni of the Italian Mathematical Union. It should be noted that this book is neither a comprehensive text in algebraic topology nor is it a monograph on simplicial objects in the modern sense. Its focus is instead on the role of finite simplicial structures, and the algebraic topology deriving from them.
This book describes the construction of algebraic models which represent the operations of the double entry accounting system. It gives a novel, comprehensive, proof based treatment of the topic, using such concepts from abstract algebra as automata, digraphs, monoids and quotient structures.
