This book offers an up-to-date, comprehensive account of determinantal rings and varieties, presenting a multitude of methods used in their study, with tools from combinatorics, algebra, representation theory and geometry.After a concise introduction to Gröbner and Sagbi bases, determinantal ideals are studied via the standard monomial theory and the straightening law. This opens the door for representation theoretic methods, such as the Robinson–Schensted–Knuth correspondence, whi...

Combinatorics and Algebraic Geometry have enjoyed a fruitful interplay since the nineteenth century. Classical interactions include invariant theory, theta functions and enumerative geometry. The aim of this volume is to introduce recent developments in combinatorial algebraic geometry and to approach algebraic geometry with a view towards applications, such as tensor calculus and algebraic statistics. A common theme is the study of algebraic varieties endowed with a rich combinatorial str...

In un mondo dove il settore dell’abbigliamento è ormai dominato dal fast fashion che propina solo cliché a basso costo, ha ancora senso parlare di eleganza? E di eleganza classica maschile? Questo libro, attraverso una serie di domande di difficoltà crescente e la presentazione di cinque “profili” inediti, guida il lettore nel mondo dello stile e dell’eleganza classica maschile, con particolare focus sull’esperienza dell’Alta Sartoria su misura. Le 1.000 domande contenute nel libro (suddiv...

Os trabalhos temáticos abordaram basicamente as definições de fato gerador, não-cumulatividade, contribuintes e responsáveis, obrigações acessórias e penalidades afeitas ao Imposto sobre Bens e Serviços (IBS) que se pretendia instituir.

This book presents four lectures on Rees rings and blow-ups, Koszul modules with applications to syzygies, Gröbner bases and degenerations, and applications of Adams operations.Commutative Algebra has witnessed a number of spectacular developments in recent years, including the resolution of long-standing problems; the new techniques and perspectives are leading to an extraordinary transformation in the field.The material contained in this volume, based on lectures given at...

This volume collects contributions by leading experts in the area of commutative algebra related to the INdAM meeting “Homological and Computational Methods in Commutative Algebra” held in Cortona (Italy) from May 30 to June 3, 2016 . The conference and this volume are dedicated to Winfried Bruns on the occasion of his 70th birthday. In particular, the topics of this book strongly reflect the variety of Winfried Bruns’ research interests and his great impact on commutative algebra as well ...
