Theta Invariants of Euclidean Lattices and Infinite-Dimensional Hermitian Vector Bundles over Arithmetic Curves
Jean-Benoît Bost
Springer Nature Switzerland AG
2020
sidottu
This book presents the most up-to-date and sophisticated account of the theory of Euclidean lattices and sequences of Euclidean lattices, in the framework of Arakelov geometry, where Euclidean lattices are considered as vector bundles over arithmetic curves. It contains a complete description of the theta invariants which give rise to a closer parallel with the geometric case. The author then unfolds his theory of infinite Hermitian vector bundles over arithmetic curves and their theta invariants, which provides a conceptual framework to deal with the sequences of lattices occurring in many diophantine constructions.The book contains many interesting original insights and ties to other theories. It is written with extreme care, with a clear and pleasant style, and never sacrifices accessibility to sophistication.

Geometric Invariant Theory, Holomorphic Vector Bundles and the Harder-Narasimhan Filtration
Alfonso Zamora Saiz; Ronald A. Zúñiga-Rojas
Springer Nature Switzerland AG
2021
nidottu
This book introduces key topics on Geometric Invariant Theory, a technique to obtaining quotients in algebraic geometry with a good set of properties, through various examples. It starts from the classical Hilbert classification of binary forms, advancing to the construction of the moduli space of semistable holomorphic vector bundles, and to Hitchin’s theory on Higgs bundles. The relationship between the notion of stability between algebraic, differential and symplectic geometry settings is also covered.Unstable objects in moduli problems -- a result of the construction of moduli spaces -- get specific attention in this work. The notion of the Harder-Narasimhan filtration as a tool to handle them, and its relationship with GIT quotients, provide instigating new calculations in several problems. Applications include a survey of research results on correspondences between Harder-Narasimhan filtrations with the GIT picture and stratifications of the moduli space of Higgs bundles.Graduate students and researchers who want to approach Geometric Invariant Theory in moduli constructions can greatly benefit from this reading, whose key prerequisites are general courses on algebraic geometry and differential geometry.
Manifolds, Vector Fields, and Differential Forms
Gal Gross; Eckhard Meinrenken
Springer International Publishing AG
2023
nidottu
This textbook serves as an introduction to modern differential geometry at a level accessible to advanced undergraduate and master's students. It places special emphasis on motivation and understanding, while developing a solid intuition for the more abstract concepts. In contrast to graduate level references, the text relies on a minimal set of prerequisites: a solid grounding in linear algebra and multivariable calculus, and ideally a course on ordinary differential equations. Manifolds are introduced intrinsically in terms of coordinate patches glued by transition functions. The theory is presented as a natural continuation of multivariable calculus; the role of point-set topology is kept to a minimum. Questions sprinkled throughout the text engage students in active learning, and encourage classroom participation. Answers to these questions are provided at the end of the book, thus making it ideal for independent study. Material is further reinforced with homework problems ranging from straightforward to challenging. The book contains more material than can be covered in a single semester, and detailed suggestions for instructors are provided in the Preface.
Search for Invisible Decays of the Higgs Boson Produced via Vector Boson Fusion at the LHC with CMS Run 2 data
Alp Akpinar
Springer International Publishing AG
2024
sidottu
This thesis reports the latest measurements on one of the leading dark matter searches conducted by the Compact Muon Solenoid (CMS) experiment at CERN, leading to some of the most stringent constraints on hypothesized interactions between the Higgs boson and dark matter. The thesis also includes further research about the future outlook of the experiment, including exploratory research on the adaptation of deep learning models in future dark matter analyses to improve analysis sensitivity, and the design of a new type of data processing hardware to be used in the next phase of the CMS experiment.
An Invitation to Hypoelliptic Operators and Hörmander's Vector Fields
Marco Bramanti
Springer International Publishing AG
2013
nidottu
?Hörmander's operators are an important class of linear elliptic-parabolic degenerate partial differential operators with smooth coefficients, which have been intensively studied since the late 1960s and are still an active field of research. This text provides the reader with a general overview of the field, with its motivations and problems, some of its fundamental results, and some recent lines of development.
The Open Mapping and Closed Graph Theorems in Topological Vector Spaces
Taqdir Husain
Springer-Verlag
1965
nidottu
THE main purpose of writing this monograph is to give a picture of the progress made in recent years in understanding three of the deepest results of Functional Analysis-namely, the open-mapping and closed graph theorems, and the so-called Krein-~mulian theorem. In order to facilitate the reading of this book, some of the important notions and well-known results about topological and vector spaces have been collected in Chapter 1. The proofs of these results are omitted for the reason that they are easily available in any standard book on topology and vector spaces e.g. Bourbaki [2], Keiley [18], or Köthe [22]. The results of Chapter 2 are supposed to be weil known for a study of topological vector spaces as weil. Most of the definitions and notations of Chapter 2 are taken from Bourbaki's books [3] and [4] with some trimming and pruning here and there. Keeping the purpose of this book in mind, the presentation of the material is effected to give a quick resume of the results and the ideas very commonly used in this field, sacrificing the generality of some theorems for which one may consult other books, e.g. [3], [4], and [22]. From Chapter 3 onward, a detailed study of the open-mapping and closed-graph theorems as weil as the Krein-~mulian theorem has been carried out. For the arrangement of the contents of Chapters 3 to 7, see the Historical Notes (Chapter 8).

Seminal studies on the network traffic, revealed the certain statistical property (self-similar nature) of network traffic, and how they degrades the network performance. Markovian models are well recognized as the appropriate self-similar traffic models. Markovian arrival process (MAP) has been proposed to emulate self similarity over the desired time-scales. Markov modulated Poisson process (MMPP) a particular case of MMPP emulating self-similar traffc over different time scale is fitted by several authors using second order statistics. The two state Circulant Markov modulated Poisson process which is restricted version of two state MMPP. The CMMPP emulating self-similar traffic is fitted by equating the variance. The mean waiting time and packet loss behavior are calculated by using the models of CMMPP/M/1 CMMPP/M/1/K queuing systems wherein service time is taken to be deterministic exponential distributions. It is clear from the numerical results the time scale do have collision on delay packet loss probability. Loss probability of packets increases if H and Traffic intensity is increase. This type of analysis is useful in dimensioning the router.

La abeja occidental (Apis mellifera) es un insecto 'eusociale', que pertenece a la familia de las Hymen pteras. Las poblaciones se diferencian en reinas que producen cr as y trabajadores no reproductivos, los cuales recogen y procesan los alimentos y producen la apitoxina. El veneno de abeja est compuesto por varios p ptidos, uno de los cuales es la melitina, siendo este una prote na que posee un efecto bactericida y ayuda a mejorar el sistema inmunol gico.
