Ens plau convidar-vos a la presentació del llibre del professor Josep Maria Brunat, Matemàtiques Clàssiques que tindrà lloc dimecres 2 de març a les 12h30 a la sala d'actes de la Facultat. 

El llibre, editat dins la Col·lecció FME, té format digital accessible en obert a l’UPCommons, i és una selecció de trenta temes diversos que formen part de la cultura matemàtica general, però que sovint no s’expliquen als estudis de grau.

Adjuntem l'enllaç del llibre: http://hdl.handle.net/2117/83181

Esperem que la publicació sigui del vostre interès i que ens acompanyeu en l'acte de presentació.

Salutacions cordials,

Jaume Franch
Degà de la Facultat de Matemàtiques i Estadística de la UPC

Abstract

We will discuss the following problem: Suppose we have two directed graphs, G_1 and G_2, with labels in a set of constants A and a set of variables X. Each G_i has an initial vertex and a set of accepting vertices. We want to find a map f from X to A* so that G_1 and G_2 accept the same language once we substitute each x in X by f(x).

Abstract: For a polygonal domain of h holes with a total of n vertices, we present algorithms that compute the L1 geodesic diameter in O(n^2+h^4) time and the L1 geodesic center in O((n^4+n2 h^4)α(n)) time, where α(·) denotes the inverse Ackermann function. No algorithms were known for these problems before. For the Euclidean counterpart, the best algorithms compute the geodesic diameter in O(n^7.73) or O(n^7(h + log n)) time, and compute the geodesic center in O(n^12+ε) time. Therefore, our algorithms are much faster than the algorithms for the Euclidean problems. Our algorithms are based on several interesting observations on L1 shortest paths in polygonal domains.

Abstract

The Hardy-Weinberg law is a cornerstone principle of modern genetics. The law is more than a century old, and was independently stated in 1908 by the English mathematician Godfrey Hardy and the German physician Wilhelm Weinberg. The law states that, in the absence of disturbing factors (migration, differential survival and others) allele and genotype frequencies in a biological population will achieve equilibrium values within one generation and remain stable afterwards. The latter condition is known as Hardy-Weinberg equilibrium (HWE).

The principle is still relevant today, as testing markers for HWE is a standard step in almost all genetic studies. It is known that deviation from equilibrium is often associated with genotyping errors (misclassification of homozygotes as heterozygotes or the reverse), and equilibrium testing is an effective device to detect such errors. However, disequilibrium can also arise from other causes.

Moreover, Hardy-Weinberg equilibrium is typically assumed in many other statistical procedure that use genetic marker data, such as gene-disease association studies, relatedness investigations, and others. The HWE law has been a topic of intense research, and there are hundreds of research papers dedicated to it. Research related to the principle continues, as new types of genetic data arise. Pearson's chi-square test has been the most popular procedure to test genetic markers for equilibrium for decades, though nowadays computer-intensive exact procedures have become more and more popular.

In this talk I will explain some basic genetics, address the issue of statistically testing markers for Hardy-Weinberg equilibrium in large genomic databases, and comment upon recent work related to markers that reside on the X chromosome.
