20062007 Program
See http://www.ima.umn.edu/20062007 for a full description of the 20062007 program on Applications of Algebraic Geometry.
Microsoft has joined the IMA as a Participating Corporation. Microsoft's representative on the Industrial Advisory Board is Jennifer Chayes, Manager of the Theory Group and Research Area Manager for Mathematics and Theoretical Computer Science Microsoft Research.
The IMA staff are now mainly located in our newly remodeled first floor offices in Lind Hall. The future visitors of the IMA can check out an access card from the IMA office in 114 Lind Hall to visit the fourth floor as the doors and elevator accessing the fourth floor are kept locked all day.
IMA welcomes Laureen Ross McCalib who has joined the Institute for Mathematics and its Applications as assistant to the Director.

Chandrajit L. Bajaj (University of Texas)  Algebraic splines for molecular modeling 
Abstract: This talk shall describe a survey of algebraic spline (Aspline and Apatch) construction techniques for capturing molecular surfaces and implicit solvation shells (models for molecules in their watery environment). These molecular surfaces are obtained from either atomic 3D coordinates (scattered data) of the molecule, or segmented 3D electron microscopy maps (dense data). For 3D maps at 5 20 Angstrom resolution, I shall also present algebraic spline algorithms to detect and represent secondary (helices, sheets) and/or tertiary (sandwiches, barrels, etc.) structural molecular models. For these latter algorithms, we employ techniques from computational algebraic geometry and differential topology, especially the computation of stable/unstable manifolds of certain critical points of distance functions of molecular surface boundaries.

Frederic Cazals (Institut National de Recherche en Informatique Automatique (INRIA))  Geometric and topological inference in the non linear realm: on the importance of singularity theory 
Abstract: In the non linear realm, a powerful way to describe complex shapes is in terms of stratifications, that is topological disks together with the proper incidences, so as to define some kind of complex (cell, CW, etc). In particular, singularity theory provides a convenient way to specify such incidences through local normal forms, the parametric form of the topological disks depending on the particular problem investigated. We shall review two examples illustrating this framework in 3D : the detection of loci of extremal curvature of smooth surfaces (the socalled ridges), and the calculation of the MorseSmale complex of the distance function to points in 3D space (the socalled flow complex). We shall conclude with perspectives arising in trying to generalize such approaches in higher dimension.  
David A. Cox (Amherst College)  Topics in curve and surface implicitization 
Abstract: This lecture will discuss several topics related to curve and surface implicitization, including the structure of the moving curve ideal, the construction of mubases for surface implicitizations, and the resultant of the mubasis.  
Carlos D'Andrea (University of Barcelona)  Bezout's theorem and implicitization 
Abstract: This is a joint work with Martin Sombra. The computation of the implicit equations of polynomial and rational parametrizations is always a hot topic in Computational Algebraic Geometry and CAGD. Recently, a lot of attention has been given to the computation of the Newton Polytope of the implicit equation, given the supports of the parametrization (sparse philosophy). In this talk, we will show how the use of classical intersection theory in the torus can give us nontrivial information about this Newton Polytope. As an application of these results, we can give a complete description of the Newton Polytope of the implicit equation of a generic plane rational curve.

Kenneth R. Driessel (Iowa State University)  Real algebraic geometry tutorial: Border bases (continued) 
Abstract: We discussed border bases on May 21 and June 7 June 14 and June 21. We shall continue that discussion. I continue to look at the following books and papers: Kehrein, A; Kreuzer, M. and Robbiano, L. (2005) "An algebraist's view of border basis", in Dickenstein, A. and Emiris, I.Z. (2005), Solving Polynomial Equations}, Springer. Mourrain, B. (1999) "A new criterion for normal form algorithms", in Applied algebra, algebraic algorithms and errorcorrecting codes (Honolulu, HI, 1999), 430443, Lecture Notes in Computer Science, 1719, Springer. Stetter, H.J. (2004) Numerical Polynomial Algebra, SIAM. I plan to mainly follow the last few chapters in the book by Stetter. As usual, I shall try to minimize prerequisites.  
Anna Gilbert (University of Michigan)  Algorithms for Compressed Sensing, II 
Abstract: What do these algorithms all have in common? What are the common goals of the problems and how do they achieve them? I will discuss several known techniques and open problems.  
Manfred Husty (LeopoldFranzens Universität Innsbruck)  Application of algebraic geometry to kinematics 
Abstract: Algebraic methods in connection with classical multidimensional geometry have proven to be very efficient in the computation of direct and inverse kinematics of mechanisms as well as the explanation of strange, pathological behaviour of mechanical systems. Generally one can say that every planar, spherical or spatial mechanism having revolute or prismatic joints can be described by systems of algebraic equations. In this talk we give an overview of the results achieved within the last years using algebraic geometric methods, geometric preprocessing and numerical analysis. We provide the mathematical and geometrical background, like Study's parametrization of the Euclidean motion group, the ideals belonging to mechanism constraints The methods are explained with different examples from mechanism analysis and synthesis.  
Gabriela Jeronimo (University of Buenos Aires)  Algebraic geometry and applications seminar: A symbolic approach to sparse elimination 
Abstract: Sparse elimination is concerned with systems of polynomial equations in which each equation is given by a polynomial having nonzero coefﬁcients only for those monomials lying in a prescribed set. We will discuss a new symbolic procedure for solving zerodimensional sparse polynomial systems by means of deformation techniques. Roughly speaking, a deformation method to solve a zerodimensional polynomial equation system works as follows: the input system is regarded as a member of a parametric family of zerodimensional systems. Then, the solutions to a particular parametric instance which is ``easy to solve'' are computed and, finally, these solutions enable one to recover the solutions of the original system. The algorithm combines the polyhedral deformation introduced by Huber and Sturmfels with symbolic techniques relying on the NewtonHensel lifting procedure. Its running time can be estimated mainly in terms of the input length and two invariants related to the combinatorial structure underlying the problem.  
Ileana Streinu (Smith College)  Geometric representation of rigidityrelated matroids 
Abstract: Sparsity matroids generalize the combinatorics behind several types of rigidity (2D barandjoint, arbitrary dimension bodyandbar, etc.). A conspicuous open problem is to find geometric representations for ALL of them. We present some partial answers. This is joint work with Louis Theran from UMass Amherst.  
Ming Zhang (University of Texas)  Bezier subdivision for inverse molecular kinematics 
Abstract: Conformational searching is a core task in inverse molecular kinematics. Algorithmic improvements affecting either the speed or quality of conformational searching will have a profound impact on applications including ligandreceptor docking, ab initio prediction of protein structure, and protein folding. In this talk, we focus on a specific geometryconstrained conformational searching problem, where some feature atoms have prespecified target positions. Using Bezier subdivision, we present a method to locate and approximate the solutions of the equations derived from constraints on the feature atoms. The conformations corresponding to these solutions are all the conformations satisfying the target constraints. Three implementations of the subdivision method taking advantage of the sparsity of the coefficients of the polynomial equations are presented and the results are compared.
