The N 2 Wonderland

This book presents, in a unifying perspective, the topics related to N=2 supersymmetry in two dimensions. Beginning with the K„hler structure of D=4 supergravity Lagrangians, through the analysis of string compactifications on Calabi-Yau manifolds, one reaches the heart of the matter with the chiral ring structure of N=2 conformal field theories and its relation to topological field theory models and Landau-Ginzburg models. In addition, mirror symmetry, topological twists and Picard-Fuchs equations are discussed.

This graduate-level primer presents a tutorial introduction to and overview of N = 2 supergravity theories - with 8 real supercharges and in 4, 5 and 6 dimensions. First, the construction of such theories by superconformal methods is explained in detail, and relevant special geometries are obtained and characterized. Following, the relation between the supergravity theories in the various dimensions is discussed. This leads eventually to the concept of very special geometry and quaternionic-Kähler manifolds. This concise text is a valuable resource for graduate students and young researchers wishing to enter the field quickly and efficiently.

Helping you invest your money most profitably It's not easy to make the right investment decisions. First of all, there are so many investment avenues, each promising different returns and carrying different risks. To add further complexity, there is the fact that different investments are treated differently by the taxman; some attracting higher taxes, others enjoying tax concessions — and the tax laws keep changing all the time. Moreover, each person has his or her own unique financial needs and risk profile. What is tonic for one may prove to be poison for another. Equally, new avenues and instruments of investment keep arising and old ones setting on the horizons of the wonderland of investment. Some of the existing bright stars may suddenly become black holes. The interest rates have a habit of bobbing up and down. This will surely need a change in your portfolio mix. The bestselling book is packed with a wealth of investment information and guidance about the various investment avenues, their risks and profitability, and their tax implications. Not just that. Based on their 40-plus years of investment advisory expertise, the authors offer those rare insights that will truly help you invest your money most profitably.

Falsely accused of murdering his classmates and sentenced to death in Deadman Wonderland, Ganta begins to learn more about life inside the prison walls. Upon hearing that the Red Man, the strange being that killed his friends, is in the G Ward, Ganta heads there seeking answers—and revenge. Instead he finds a mysterious man who calls him “Woodpecker.” -- VIZ Media

Revolution is rising in Wonderland. Dinah’s battle has begun. Colleen Oakes’s twisted reimagining of the Queen of Hearts origin story continues in this thrilling sequel, Blood of Wonderland. Dinah has been exiled from Wonderland. The vicious father she always feared has framed her for the brutal murder of her brother and turned the kingdom against her. Now hiding in the lush and mysterious Twisted Wood with only her war steed at her side, Dinah is faced with a choice—to leave Wonderland forever, or stay and fight her father for the throne. When a chance encounter with one of her father’s long-lost enemies brings Dinah more allies than she ever could have imagined, war starts to feel inevitable. But before Dinah can lead her people into combat, she must confront certain truths about her heart and her destiny—no matter how dark those truths may be. Don’t miss War of the Cards, the epic conclusion to the Queen of Hearts trilogy.

During the last five years, after the first meeting on OC Quaternionic Structures in Mathematics and PhysicsOCO, interest in quaternionic geometry and its applications has continued to increase. Progress has been made in constructing new classes of manifolds with quaternionic structures (quaternionic Knhler, hyper-Knhler, hyper-complex, etc.), studying the differential geometry of special classes of such manifolds and their submanifolds, understanding relations between the quaternionic structure and other differential-geometric structures, and also in physical applications of quaternionic geometry. Some generalizations of classical quaternion-like structures (like HKT structures and hyper-Knhler manifolds with singularities) appeared naturally and were studied. Some of those results are published in this book. Contents: Hypercomplex Structures on Special Classes of Nilpotent and Solvable Lie Groups (M L Barberis); Twistor Quotients of HyperKnhler Manifolds (R Bielawski); Quaternionic Contact Structures (O Biquard); A New Construction of Homogeneous Quaternionic Manifolds and Related Geometric Structures (V Cortes); Quaternion Knhler Flat Manifolds (I G Dotti); A Canonical HyperKnhler Metric on the Total Space of a Cotangent Bundle (D Kaledin); Special Spinors and Contact Geometry (A Moroianu); Brane Solitons and Hypercomplex Structures (G Papadopoulos); Hypercomplex Geometry (H Pedersen); Examples of HyperKnhler Connections with Torsion (Y S Poon); A New Weight System on Chord Diagrams via HyperKnhler Geometry (J Sawon); Vanishing Theorems for Quaternionic Knhler Manifolds (U Semmelmann & G Weingart); Weakening Holonomy (A Swann); Special Knhler Geometry (A Van Proeyen); Singularities in HyperKnhler Geometry (M Verbitsky); and other papers. Readership: Researchers and graduate students in geometry, topology, mathematical physics and theoretical physics."

Narcoleptic Southie PI Mark Genevich returns in this sequel to The Little Sleep from the Bram Stoker Award–winning author of Survivor Song and The Cabin at the End of the World. Like most private eyes, Mark Genevich is something of a lone wolf. So group therapy isn’t a great fit. But his landlord/mother is convinced it will help his narcolepsy—ignoring the fact that his disorder is a physical condition. Truth is, he has the time. It’s been a year and a half since his last big case, or any case. It’s never a wise choice to go on a two-day bender with someone you meet in group therapy, but there’s something about Gus that intrigues Genevich. And when his new drinking buddy asks him to protect a female friend who’s being stalked, the PI finally has a case. Unfortunately, he’s about to sleepwalk right into a very real nightmare. Before long he’s a suspect in an arson investigation and running afoul of everyone from the cops to a litigious lawyer and a bouncer with anger management issues. Genevich must keep his wits about him—always a challenge for a detective prone to unexpected blackouts and hallucinations—to solve the crime and live to show up at his next therapy session. In Paul Tremblay’s follow-up to The Little Sleep, unreliable narrator Mark Genevich once again leads readers on a surreal and suspenseful wild ride through the mean streets of South Boston and his own dreamlike reality.
