"Verónica Gerber writes with a luminous intimacy; her novel is clever, vibrant, moving, profoundly original. Reading it made me feel as if the world had been rebuilt." —Francisco Goldman "From the very beginning, Verónica Gerber set out to write a novel that would end up at a loss for words. She alone could achieve this feat: because she's a visual artist who takes everything she reads in as concentric circles threaded with color, and because she writes essays on painters who write across canvasses and writers who paint plots from the realities of life. . . . She alone could bring the necessary silence to a novel so perfect it ended up leaving me speechless as well." —Jorge F. Hernández How do you draw an affair? A family? Can a Venn diagram show the ways overlaps turn into absences, tree rings tell us what happens when mothers leave? Can we fall in love according to the hop skip of an acrostic? Empty Set is a novel of patterns, its young narrator's attempt at making sense of inevitable loss, tracing her way forward in loops, triangles, and broken lines. Verónica Gerber Bicecci is a visual artist who writes. In 2013 she was awarded the third Aura Estrada prize for literature. She is an editor with Tumbona Ediciones, a publishing cooperative with a catalogue that explores the intersections between literature and art.

Accessible approach to set theory for upper-level undergraduates poses rigorous but simple arguments. Topics include classes and sets, functions, natural and cardinal numbers, arithmetic of ordinal numbers, and more. 1971 edition with new material by author.

From the Preface to the first edition (1906): "A few of the most modern books on the Theory of Functions devote some pages to the establishment of certain results belonging to our subject, and required for the special purposes in hand... But we may fairly claim that the present work is the first attempt at a systematic exposition of the subject as a whole."

In recent years rough set theory has attracted the attention of many researchers and practitioners all over the world, who have contributed essentially to its development and applications. Weareobservingagrowingresearchinterestinthefoundationsofroughsets, including the various logical, mathematical and philosophical aspects of rough sets. Some relationships have already been established between rough sets and other approaches, and also with a wide range of hybrid systems. As a result, rough sets are linked with decision system modeling and analysis of complex systems, fuzzy sets, neural networks, evolutionary computing, data mining and knowledge discovery, pattern recognition, machine learning, and approximate reasoning. In particular, rough sets are used in probabilistic reasoning, granular computing (including information granule calculi based on rough mereology), intelligent control, intelligent agent modeling, identi?cation of autonomous s- tems, and process speci?cation. Methods based on rough set theory alone or in combination with other - proacheshavebeendiscoveredwith awide rangeofapplicationsinsuchareasas: acoustics, bioinformatics, business and ?nance, chemistry, computer engineering (e.g., data compression, digital image processing, digital signal processing, p- allel and distributed computer systems, sensor fusion, fractal engineering), de- sion analysis and systems, economics, electrical engineering (e.g., control, signal analysis, power systems), environmental studies, informatics, medicine, mole- lar biology, musicology, neurology, robotics, social science, software engineering, spatial visualization, Web engineering, and Web mining.

Volume IV of the Transactions on Rough Sets (TRS) introduces a number of new advances in the theory and application of rough sets. Rough sets and - proximationspaceswereintroducedmorethan30yearsagobyZdzis lawPawlak. These advances have profound implications in a number of research areas such as the foundations of rough sets, approximate reasoning, arti?cial intelligence, bioinformatics,computationalintelligence, cognitivescience, intelligentsystems, datamining,machineintelligence,andsecurity. Inaddition,itisevidentfromthe papers included in this volume that the foundations and applications of rough sets is a very active research area worldwide. A total of 16 researchers from 7 countries are represented in this volume, namely, Canada, India, Norway, S- den, Poland, Russia and the United States of America. Evidence of the vigor, breadth and depth of research in the theory and applications of rough sets can be found in the 10 articles in this volume. Prof. Pawlak has contributed a treatise on the philosophical underpinnings of rough sets. In this treatise, observations are made about the Cantor notion of a set, antinomies arising from Cantor sets, the problem of vagueness (es- cially, vague (imprecise) concepts), fuzzy sets, rough sets, fuzzy vs. rough sets as well as logic and rough sets. Among the many vistas and research directions suggested by Prof. Pawlak, one of the most fruitful concerns the model for a rough membership function, which was incarnated in many di?erent forms since its introduction by Pawlakand Skowronin 1994. Recall, here, that Prof.

This Stormlight Archive discounted ebundle includes: The Way of Kings, Words of Radiance, Oathbringer The #1 New York Times bestselling epic fantasy series by Brandon Sanderson! The Stormlight Archive is the wildly imaginative epic fantasy from New York Times bestselling author Brandon Sanderson: welcome to the remarkable world of Roshar, a world of stone and storms. Uncanny tempests of incredible power sweep across the rocky terrain so frequently that they have shaped ecology and civilization alike. Roshar is shared by humans and the enigmatic, humanoid Parshendi, with whom they are at war. It has been centuries since the fall of the ten consecrated orders known as the Knights Radiant, but their Shardblades and Shardplate remain. Men trade kingdoms for Shardblades. Wars were fought for them, and won by them, but in the war against the Parshendi, the ancient weapons and armor may not be enough. Speak again the ancient oaths: Life before death. Strength before weakness. Journey before Destination. and return to men the Shards they once bore. The Knights Radiant must stand again. --- Other Tor books by Brandon Sanderson The Cosmere The Stormlight Archive The Way of Kings Words of Radiance Edgedancer (Novella) Oathbringer The Mistborn trilogy Mistborn: The Final Empire The Well of Ascension The Hero of Ages Mistborn: The Wax and Wayne series Alloy of Law Shadows of Self Bands of Mourning Collection Arcanum Unbounded Other Cosmere novels Elantris Warbreaker The Alcatraz vs. the Evil Librarians series Alcatraz vs. the Evil Librarians The Scrivener's Bones The Knights of Crystallia The Shattered Lens The Dark Talent The Rithmatist series The Rithmatist Other books by Brandon Sanderson The Reckoners Steelheart Firefight Calamity At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Leroy Brown, aka Encyclopedia Brown, is Idaville neighborhood’s ten-year-old star detective. With an uncanny knack for trivia, he solves mysteries for the neighborhood kids through his own detective agency. But his dad also happens to be the chief of the Idaville police department, and every night around the dinner table, Encyclopedia helps him solve his most baffling crimes. And with ten confounding mysteries in each book, not only does Encyclopedia have a chance to solve them, but the reader is given all the clues as well. Interactive and chock full of interesting bits of information—it’s classic Encyclopedia Brown!

This is the first monograph on codebooks and linear codes from difference sets and almost difference sets. It aims at providing a survey of constructions of difference sets and almost difference sets as well as an in-depth treatment of codebooks and linear codes from difference sets and almost difference sets. To be self-contained, this monograph covers necessary mathematical foundations and the basics of coding theory. It also contains tables of best BCH codes and best cyclic codes over GF(2) and GF(3) up to length 125 and 79, respectively. This repository of tables can be used to benchmark newly constructed cyclic codes. This monograph is intended to be a reference for postgraduates and researchers who work on combinatorics, or coding theory, or digital communications.
