It is named after the Norwegian mathematician Niels Henrik Abel (1802–1829) who found that there is no explicit formula for the roots of a general polynomial of degree five. The financial support of the Abel Prize is comparable with the Nobel Prize, i.e., about one million American dollars. Niels Henrik Abel (1802–1829) M.

  • Birational Geometry of Algebraic Varieties

    Birational Geometry of Algebraic Varieties

    Proc. Int. Cong. of Math. – 2018 Rio de Janeiro, Vol. 1 (563–588) BIRATIONAL GEOMETRY OF ALGEBRAIC VARIETIES Caucher Birkar 1 Introduction This is a report on some of the main developments in birational geometry in recent years focusing on the minimal model program, Fano varieties, singularities and related topics, in characteristic zero. This is not a comprehensive survey of all advances in birational geometry, e.g. we will not touch upon the positive characteristic case which is a very active area of research. We will work over an algebraically closed field k of characteristic zero. Varieties are all quasi-projective. Birational geometry, with the so-called minimal model program at its core, aims to classify algebraic varieties up to birational isomorphism by identifying “nice” elements in each birational class and then classifying such elements, e.g study their moduli spaces. Two varieties are birational if they contain isomorphic open subsets. In dimension one, a nice element in a birational class is simply a smooth and projective element. In higher dimension though there are infinitely many such elements in each class, so picking a rep- resentative is a very challenging problem. Before going any further lets introduce the canonical divisor. 1.1 Canonical divisor. To understand a variety X one studies subvarieties and sheaves on it. Subvarieties of codimension one and their linear combinations, that is, divisors play a crucial role. Of particular importance is the canonical divisor KX . When X is smooth this is the divisor (class) whose associated sheaf OX (KX ) is the canonical sheaf !X := det ΩX where ΩX is the sheaf of regular differential forms.
  • 1 Getting a Knighthood

    1 Getting a Knighthood

    Getting a knighthood (Bristol, June 1996) It's unreal, isn't it? I've always had a strong sense of the ridiculous, of the absurd, and this is working overtime now. Many of you must have been thinking, ‘Why Berry?’ Well, since I am the least knightly person I know, I have been asking the same question, and although I haven't come up with an answer I can offer a few thoughts. How does a scientist get this sort of national recognition? One way is to do something useful to the nation, that everyone agrees is important to the national well- being or even survival. Our home-grown example is of course Sir Charles Frank's war work. Or, one can sacrifice several years of one's life doing high-level scientific administration, not always received with gratitude by the scientific hoi polloi but important to the smooth running of the enterprise. Sir John Kingman is in this category. Another way – at least according to vulgar mythology – is to have the right family background. Well, my father drove a cab in London and my mother ruined her eyes as a dressmaker. Another way is to win the Nobel Prize or one of the other huge awards like the Wolf or King Faisal prizes, like Sir George Porter as he then was, or Sir Michael Atiyah. The principle here I suppose is, to those that have, more shall be given. I don't qualify on any of these grounds. The nearest I come is to have have won an fairly large number of smaller awards.

He was a 14 th century physician. No information is available on his birth and death – only “Al-Mughni”, a book, has been left to make him famous in surgical and medical knowledge. Methods: We used desk and historical research methods in this research, with a historical approach. This commonly used research method in human sciences was used to criticize and study the birthplace and works of Sadid al-Din Kazeroni. Results and Conclusion: Sadid al-Din Kazeroni discussed the exact issues in the field of anatomy, surgery, and gynecology. He was fluent in pharmacology. In his pharmacology book, for the first time, he named drugs considered necessary before and after surgery. In this study, we reviewed the biography and introduction of the works and reviewed “Al-Mughni”, a book on breast cancer.

    A MODEL FOR RANDOM THREE{MANIFOLDS BRAM PETRI AND JEAN RAIMBAULT Abstract. We study compact three-manifolds with boundary obtained by randomly gluing together truncated tetrahedra along their faces. We prove that, asymptotically almost surely as the number of tetrahedra tends to infinity, these manifolds are connected and have a single boundary component. We prove a law of large numbers for the genus of this boundary component, we show that the Heegaard genus of these manifolds is linear in the number of tetrahedra and we bound their first Betti number. We also show that, asymptotically almost surely as the number of tetrahedra tends to infinity, our manifolds admit a unique hyperbolic metric with totally geodesic boundary. We prove a law of large numbers for the volume of this metric, prove that the associated Laplacian has a uniform spectral gap and show that the diameter of our manifolds is logarithmic as a function of their volume. Finally, we determine the Benjamini{Schramm limit of our sequence of random manifolds. 1. Introduction 1.1. Context. Random constructions of compact manifolds can be seen as an analogue of the well-established theory of random graphs and serve similar purposes. First of all, they make the notion of a \typical" manifold rigorous. Secondly, they can be used as a testing ground for conjectures of which the proof is still out of reach. Finally, there is what is often called the probabilistic method { using probability theory to prove the existence of objects with extremal properties. In this paper we are mostly interested in the first aspect.
