**Cohen-Macaulay modules over Cohen-Macaulay rings**

The aim of those notes is to provide an explanation for intimately a few issues at the intersection of commutative algebra, illustration concept and singularity conception. they're in accordance with lectures given in Tokyo, but additionally comprise new learn. it's the first cohesive account of the realm and may supply an invaluable synthesis of contemporary study for algebraists.

**Introduction to octonion and other non-associative algebras in physics**

During this publication, the writer applies non-associative algebras to physics. Okubo covers themes starting from algebras of observables in quantum mechanics and angular momentum and octonions to department algebra, triple-linear items and YangSHBaxter equations. He additionally discusses the non-associative gauge theoretic reformulation of Einstein's basic relativity thought.

**Ockham Algebras (Oxford Science Publications)**

Ockham algebras--the ordinary generalization of a well-known and demanding idea of a boolean algebra--has an unlimited quantity of subvarieties, together with these of de Morgan, Stone, and Kleene algebras. This e-book, the 1st unified account of the topic, info the various vital breakthroughs that experience happened during this region of lattice idea because Berman's pioneering paintings in 1977.

The collage of Virginia (Charlottesville) hosted a world convention on Infinite-dimensional features of illustration concept and functions. This quantity includes papers because of the mini-courses and talks given on the meeting.

Beyond the innovations and ideas on the topic of illustration conception, the ebook demonstrates connections to quantity conception, algebraic geometry, and mathematical physics. particular themes lined comprise Hecke algebras, quantum teams, infinite-dimensional Lie algebras, quivers, modular representations, and Gromov-Witten invariants.

The booklet is acceptable for graduate scholars and researchers attracted to illustration theory.

Readership: Graduate scholars and examine mathematicians drawn to illustration idea.
