Subject: Modulo 2-pi data fitting

Does anyone out there have pointers to literature on computational
methods for modulo 2-pi data fitting? The 2-pi wrap-around arises in
an optics application with monochromatic light when data is scaled by
dividing through by wavelength to convert optical path difference to
phase. We desire an optimal fit of a relatively low degree polynomial
(degree less than 5) to phase data. Minimization in the l-infinity
(minimax) norm is preferred, although l-2 norm (least squares)
minimization is acceptable. No penalty should be incurred by 2-pi
jumps, e.g., p(x)=0 and p(x)=2*pi should produce the same fit-to-data

Thanks in advance for your help.

Subject: Tensor Decompositions and Applications, Belgium, Jan 2016

Third Workshop on Tensor Decompositions and Applications (TDA 2016)
January 18-22, 2016 Leuven, Belgium

Extended deadline for abstract submission: Sept. 15.

Higher-order tensor methods are intensively studied in many
disciplines nowadays. The developments gradually allow us to move from
classical vector and matrix based methods in applied mathematics and
mathematical engineering to methods that involve tensors of arbitrary
order. This step from linear transformations, quadratic and bilinear
forms to polynomials and multilinear forms is relevant for the most
diverse applications. Furthermore, tensor methods have firm roots in
multilinear algebra, algebraic geometry, numerical mathematics and

This workshop will bring together researchers investigating tensor
decompositions and their applications. It will feature a series of
invited talks by leading experts and contributed presentations on
specific problems. TDA 2016 is held in cooperation with the Society
for Industrial and Applied Mathematics (SIAM) and has been endorsed by
the International Linear Algebra Society (ILAS). Part of the workshop
is supported by the ERC Advanced Grant BioTensors.
