Description

Mathematical methods based on the variational approach are successfully used in a broad range of applications, especially those fields that are oriented on partial differential equations (PDEs). 

Our problem area addresses a class of nonlinear variational problems described by all kinds of dynamic and static PDEs, inverse and ill-posed problems, nonsmooth and nonconvex optimization, and optimal control including shape and topology optimization. Within these directions, we focus but are not limited to singular and unilaterally constrained problems arising in mechanics, which are governed by complex systems of generalized variational equations and inequalities. 

While standard mathematical tools are not applicable here, we aim at a non-standard well-posedness analysis, asymptotic and approximation techniques including homogenization, which are successful within the primal as well as the dual variational formalism. 

In a broad scope, the minisymposium objectives are directed toward advances that are attained in the mathematical theory of nonsmooth variational problems, its numerical computation and application to engineering sciences.

Description

Since the classical text written by Szegő in 1939, which set the foundations for the theory for orthogonal polynomials on the real line and on the unit circle, great advances both in the general theory and in the interaction with other areas of mathematics take place. Among them, we highlight here the links with numerical analysis (via classical Gaussian integration and their extensions as well as spectral methods for boundary value problems), approximation theory, spectral theory of differential operators, or potential theory in the complex plane. 

In the last few years, a very fruitful area of research for the mathematical community working in orthogonal polynomials is related to the theory of random matrices, determinantal random processes and integrable systems. Structural properties of polynomials in the framework of standard L2 orthogonality with respect to a Borel measure (or a weight function) have been deeply studied for other patterns of orthogonality like multiple orthogonal polynomials, orthogonal polynomials in several variables or Sobolev orthogonal polynomials.

The aim of this mini-symposium is to bring together international experts in different aspects of the theory of orthogonal polynomials, from analytic to numerical aspects with a special emphasis on their applications, and give the community more visibility in an international meeting that has a larger scope than the regular conferences on the topic.

Description

Low-dimensional topology is the study of manifolds of dimension 4 or lower, such as our physical universe and spacetime. This subject had its origins in Europe with the work of such luminaries as Poincaré, Heegaard, Seifert and Möbius. Dramatic developments in the later 20th century came from the work of, in particular, Donaldson, Freedman, Gromov, Ozsváth, Szabó, and Witten. Today the subject is the focus of a tremendous amount of worldwide activity and has been enjoying a resurgence across Europe in the last two decades. Modern methods in low-dimensional topology draw on and are deeply connected with many other subjects including physics, differential geometry, combinatorics and representation theory.

This mini-symposium will bring together international experts in the subject including some of the most promising early career mathematicians working in the field. A range of topics and their connections to each other and other areas of mathematics will be explored. These will include symplectic and contact topology, Heegaard Floer homology, Seiberg-Witten theory and monopole Floer homology, and knot theory including Khovanov homology.

 

Research area: 57 Manifolds and cell complexes

Description

G2-series are about strong and beautiful mathematics, especially those involving group actions on combinatorial objects. The main goal of G2G2-Minisymposia is to bring together researchers from different mathematical fields to exchange knowledge and results in a broad range of topics relevant to graph theory and group theory with connections to algebraic combinatorics,finite geometries, designs, computational discrete algebra, vertex operator algebras, topological graph theory, network analysis, and their applications in physics, chemistry, biology.

G2G2-Minisymposia is associated with G2G2-Summer School which will be held in Rogla, 29 June - 4 July, as an internal satellite event of 8ECM.

 

Research area: Combinatorics - 05E, 05A, 05B, 05C, 20B, 20C, 20E, 20F, 68R, 68W

Description

The minisymposium is devoted to recent advances in topological methods in differential equations. The topological approach has been intensively used in the last years to study differential models arising from the life sciences.

The session will be focused on existence, bifurcation, multiplicity, localization, stability and approximation of solutions to elliptic or parabolic differential equations studied by means of topological degree, fixed point index, Conley-type indices, fixed point and critical point theories as well as dynamical systems. Particular attention will be given to real world applications.

Description

Operator algebras form a flourishing field of mathematics with strong ties to functional analysis, harmonic analysis, topology, (non-commutative) geometry, group theory and dynamical systems.

Operator algebras come in two flavors: topological and continuous aspects are captured by C*-algebras, while measurable and ergodic phenomena appear in von Neumann algebras. In both areas, important progress was made in the past years, especially in the classification of simple nuclear C*-algebras and in the structure and classification theory of non-amenable von Neumann algebras, often given by groups and measurable dynamics.

A key feature of these developments is a continuous interaction between the traditionally quite distinct C*-algebra and von Neumann algebra approaches. Boundary actions of groups and other methods from geometric group theory play an increasingly important role in studying von Neumann algebras, while the highly developed theory of injectivity and hyperfiniteness for von Neumann algebras is crucial for the ongoing classification theory for nuclear C*-algebras.

The aim of this mini-symposium is to bring together researchers working in a diverse range of topics in operator algebras, so as to exchange a wide variety of ideas and methods, fostering a cross-pollination between these different fields of mathematics.
