Sommario/riassunto |
|
This textbook offers an introduction to abelian varieties, a rich topic of central importance to algebraic geometry. The emphasis is on geometric constructions over the complex numbers, notably the construction of important classes of abelian varieties and their algebraic cycles. The book begins with complex tori and their line bundles (theta functions), naturally leading to the definition of abelian varieties. After establishing basic properties, the moduli space of |

abelian varieties is introduced and studied. The next chapters are devoted to the study of the main examples of abelian varieties: Jacobian varieties, abelian surfaces, Albanese and Picard varieties, Prym varieties, and intermediate Jacobians. Subsequently, the Fourier–Mukai transform is introduced and applied to the study of sheaves, and results on Chow groups and the Hodge conjecture are obtained. This book is suitable for use as the main text for a first course on abelian varieties, for instance as a second graduate course in algebraic geometry. The variety of topics and abundant exercises also make it well suited to reading courses. The book provides an accessible reference, not only for students specializing in algebraic geometry but also in related subjects such as number theory, cryptography, mathematical physics, and integrable systems. |

Sommario/riassunto |

The growing world population exerts tremendous pressure on our finite food resources. Since the lion's share of the global calorie intake is reliant upon a handful of plant species like rice, wheat, maize, soybean, and potato, it is the need of the hour to expand our dietary reliance to nutritionally rich but neglected, underutilized, and yet-to-be-used wild |

plants. Such wild plants also have ethnomedicinal and biocultural significance. Owing to their ecosystem plasticity, they can be easily cultivated in diverse soil systems, including marginal, degraded, and other disturbed areas. Due to these resilient attributes, they can be considered for large-scale cultivation. However, proper biotechnological interventions are important for removing the negative traits as well as for standardizing the mass multiplication and cultivation strategies of such species for various agro-climatic regions. This Special Issue, "Wild Crop Relatives and Associated Biocultural and Traditional Agronomic Practices for Food and Nutritional Security", was dedicated to showcasing the potential wild crop varieties of nutritional significance and associated biocultural knowledge from the diverse agroecological regions of the world and also to formulating suitable policy frameworks for food and nutritional security. The novel recommendations provided by this Special Issue can serve as a stepping-stone for utilizing wild and neglected crops as supplemental foods. |
