2nd Latin American School and Workshop on Polynomial Systems
Angra dos Reis, RJ, Brasil - Feb 28 to March 4, 2005
Description and scope
The theoretical study of the solution set of polynomial equations gave rise
to classical areas in mathematics, such as Algebra or Algebraic Geometry.
Polynomial systems arising from practical or industrial applications require
a much finer study of the system structure than what is available from
classical tools.
This conference is interdisciplinary due to the nature of its object.
The analysis of equation structure involves concepts of Convex Geometry,
Symplectic Geometry, Complexity, Numerical Analysis, etc...
In addition, efficient algorithms to solve systems of polynomial equations
combine tools and concepts of Computational Algebra, Computational
Algebraic Geometry, Differential Geometry, Linear Programming, Sparse
Numerical Linear Algebra, Combinatorics, etc...
Applications of polynomial systems arise in many areas, such as
mechanical engineering, chemistry and bio-chemistry, control theory,
computer graohics, mathematical physics... Special attention here will
be given to applications to statistics.
Target audience
The school is intended for a public ranging from first year graduate
students in mathematics to research scientists. There will be a short
course and five survey lectures during the morning.
The scientific program is intended for specialists in the subject, or
researchers and students wishing to enter the subject.
Algebraic Geometry of Statistical Models
The five lectures offer an introduction to algebraic
methods in statistics. Many statistical models for
discrete data, in particular those used in machine
learning and computational biology, can be regarded
as algebraic varieties inside a high-dimensional
probability simplex. While some of these models
correspond to classical geometric objects (e.g. Segre
varieties and their secant varieties), others pose
new and unexpected challenges for algebraic geometers.
Conversely, computational algebraic geometry has a lot to
offer for statistical analysis since certain key problems,
such as computing maximum likelihood estimates and checking
identifiability, lead to systems of polynomial equations.
Bernd Sturmfels' five lectures will be based
on his forthcoming book with Lior Pachter, titled
"Algebraic Statistics for Computational Biology".
The lectures will correspond to sections in the book as follows:
Lecture 1: Statistical Models (Sections 1.1 and 1.2)
Lecture 2: Maximum Likelihood (Sections 3.3 and 1.3)
Lecture 3: Markov Models (Sections 1.4 and 1.5)
Lecture 4: Phylogenetics (Sections 2.4 and 3.5)
Lecture 5: Alignment and Inference (Sections 2.2 and 3.4)
A draft of the book is available electronically
here.
Course participants are strongly encouraged to take a look
at the above sections before traveling to Angra dos Reis.
