SGA 2020 6th Workshop on Sparse Grids and Applications

Welcome

Sparse grids were introduced under that name 30 years ago at the Sixth GAMM-Seminar in Kiel. This year the 6th workshop on Sparse Grids and Applications will celebrate the sparse grid anniversary. The workshop will return to Bonn during September 2020. It continues the workshop series on Sparse Grids and Applications: 2011 in Bonn, Germany, 2012 and 2018 in Munich, Germany, 2014 in Stuttgart, Germany, and 2016 in Miami, USA,

Sparse grids have gained increasing interest in recent years for the numerical treatment of high-dimensional problems. Where classical numerical discretization schemes fail in more than three or four dimensions, sparse grids allow to overcome the curse of dimensionality to some extent - extending the number of dimensions that can be dealt with.

The aim is to bring together researchers and practitioners using sparse grids and their variants. Both theoretical and practical aspects are highly welcome. Topics of sparse grids and their applications include

• interpolation and approximation
• complexities and error bounds
• higher-order methods
• numerical quadrature
• spatially/dimensionally adaptive refinement
• wavelets
• applications using sparse grids
• computational finance
• density estimation
• dimensionality reduction
• integral equations
• machine learning (classification, regression, clustering, ...)
• parameter scans
• (stochastic) partial differential equations
• sparse grid software
• data structures
• efficient numerical implementations

but are not limited to them.

Registration

The abstract submission is done via e-mail. The deadlines can be found at the top of the page. Follow these steps:

1. Prepare you abstract (500 words maximum) as a \(\LaTeX\) file. Please use this template.
2. Send an e-mail with your abstract to ed tod nnob-inu.sni ta 0202agsa tod b@foo.de.

After the acceptance notification date every speaker, and those we want to participate without a talk, can register for the SGA. A registration fee applies (see below).

Participation only. Please register on the SGA2020 registration website by indicating Participation only in the talk field.

Fees

Note that the workshop fee covers lunch and coffee breaks.

• Regular: t.b.c. (ca. 200-300 €)
• Student: t.b.c. (ca. 100-200 €)

The registration fee is to be paid in cash at the conference.

Financial Support

We anticipate to be able to offer some financial support for speakers and student participants who do not have enough own funds. More information will be available later.

Transportation

• By plane to Flughafen Köln Bonn. Take Bus SB60 to Bonn Hauptbahnhof (runs about every 30 minutes, 35-minute ride).
• By plane to Flughafen Düsseldorf. Take the train from Flughafen Düsseldorf to Bonn Hauptbahnhof.
• By plane to Flughafen Frankfurt. Take the train from Flughafen Frankfurt to Bonn Hauptbahnhof. Either as a (highly recommended) scenic train ride along the river Rhein or with a somewhat faster connection over Siegburg/Bonn. The train ticket may be included in or booked with your long-distance airfare.
