Download The Zeta Functions of Picard Modular Surfaces by Robert P. Janglands, Dinakar Ramakrishnan PDF

By Robert P. Janglands, Dinakar Ramakrishnan

Even if they're valuable items within the idea of diophantine equations, the zeta-functions of Hasse-Weil usually are not good understood. One huge classification of sorts whose zeta-functions are possibly close by are these hooked up to discrete teams, generically known as Shimura kinds. The recommendations concerned are tricky: illustration concept and harmonic research; the hint formulation and endoscopy; intersection cohomology and $L2$-cohomology; and abelian types with advanced multiplication.The easiest Shimura forms for which all attendant difficulties ensue are these hooked up to unitary teams in 3 variables over imaginary quadratic fields, noted during this quantity as Picard modular surfaces. The participants have supplied a coherent and thorough account of useful rules and strategies, a lot of that are novel and never formerly released.

Download Residues and Duality: Lecture Notes of a Seminar on the Work by Robin Hartshorne PDF

By Robin Hartshorne

For a few years a very good reference for algebraic geometers to profit Serre-Verdier-Grothendieck-Poincaré duality, specifically if you happen to stumbled on Deligne's therapy in SGA daunting. these days extra smooth references exist, yet none concentration as a lot on dualising complexes, making this booklet a great deal well worth the learn.

Download Several Complex Variables with Connections to Algebraic by Joseph L. Taylor PDF

By Joseph L. Taylor

This article provides an built-in improvement of the idea of a number of advanced variables and complicated algebraic geometry, resulting in proofs of Serre's celebrated GAGA theorems referring to the 2 topics, and together with purposes to the illustration concept of advanced semisimple Lie teams. It encompasses a thorough remedy of the neighborhood concept utilizing the instruments of commutative algebra, an intensive improvement of sheaf idea and the speculation of coherent analytic and algebraic sheaves, proofs of the most vanishing theorems for those different types of sheaves, and an entire evidence of the finite dimensionality of the cohomology of coherent sheaves on compact forms. The vanishing theorems have a large choice of functions and those are lined in detail.

Of specific curiosity are the final 3 chapters, that are dedicated to functions of the previous fabric to the learn of the constitution and representations of complicated semisimple Lie teams. incorporated are introductions to harmonic research, the Peter-Weyl theorem, Lie concept and the constitution of Lie algebras, semisimple Lie algebras and their representations, algebraic teams and the constitution of advanced semisimple Lie teams. All of this culminates in Miličić's evidence of the Borel-Weil-Bott theorem, which makes huge use of the fabric constructed prior within the text.

There are a number of examples and routines in each one bankruptcy. this contemporary therapy of a vintage standpoint will be a great textual content for a graduate path on numerous complicated variables, in addition to an invaluable reference for the expert.

Readership: Graduate scholars and examine mathematicians drawn to ODEs, algebraic geometry, staff concept, generalizations, and summary harmonic research.

Download Positivity in Algebraic Geometry II: Positivity for Vector by R.K. Lazarsfeld PDF

By R.K. Lazarsfeld

Quantity paintings containing a latest account on "Positivity in Algebraic Geometry".

Both volumes additionally on hand as hardcover versions as Vols. forty eight and forty nine within the sequence "Ergebnisse der Mathematik und ihrer Grenzgebiete".

A good buy of the cloth has now not formerly seemed in ebook form.

Volume II is extra on the examine level and a little extra really good than quantity I.

Volume II includes a survey of positivity for vector bundles, and strikes directly to a scientific improvement of the idea of multiplier beliefs and their applications. 

Contains many concrete examples, functions, and tips to additional developments

Download Non-Archimedean L-Functions and Arithmetical Siegel Modular by Michel Courtieu PDF

By Michel Courtieu

This ebook, now in its second version, is dedicated to the arithmetical concept of Siegel modular varieties and their L-functions. The vital object are L-functions of classical Siegel modular kinds whose unique values are studied utilizing the Rankin-Selberg approach and the motion of yes differential operators on modular kinds that have great arithmetical homes. a brand new approach to p-adic interpolation of those severe values is gifted. an incredible type of p-adic L-functions treated within the current ebook are p-adic L-functions of Siegel modular types having logarithmic development. The given building of those p-adic L-functions makes use of special algebraic homes of the arithmetical Shimura differential operator. The booklet might be very worthwhile for postgraduate scholars and for non-experts looking for a quickly method of a swiftly constructing area of algebraic quantity conception. This re-creation is considerably revised to account for the recent causes that experience emerged some time past 10 years of the most formulation for distinctive L-values when it comes to arithmetical idea of approximately holomorphic modular kinds.

Download Vector fields on singular varieties by Jean-Paul Brasselet PDF

By Jean-Paul Brasselet

Vector fields on manifolds play a big position in arithmetic and different sciences. specifically, the Poincaré-Hopf index theorem offers upward thrust to the idea of Chern periods, key manifold-invariants in geometry and topology.
It is usual to invite what's the ‘good’ idea of the index of a vector box, and of Chern sessions, if the underlying house turns into singular. The query has been explored via numerous authors leading to numerous solutions, beginning with the pioneering paintings of M.-H. Schwartz and R. MacPherson.
We current those notions within the framework of the obstruction concept and the Chern-Weil idea. The interaction among those tools is without doubt one of the major positive factors of the monograph.

Download Cubic Metaplectic Forms and Theta Functions by Nikolai Proskurin PDF

By Nikolai Proskurin

The booklet is an advent to the idea of cubic metaplectic types at the three-dimensional hyperbolic area and the author's examine on cubic metaplectic types on precise linear and symplectic teams of rank 2. the themes contain: Kubota and Bass-Milnor-Serre homomorphisms, cubic metaplectic Eisenstein sequence, cubic theta services, Whittaker capabilities. a different strategy is built and utilized to discover Fourier coefficients of the Eisenstein sequence and cubic theta services. The e-book is meant for readers, with starting graduate-level historical past, attracted to additional study within the concept of metaplectic varieties and in attainable applications.
