Universal unfoldings of Laurent polynomials and tt∗ structures
نویسندگان
چکیده
This article surveys the relations between harmonic Higgs bundles and Saito structures which lead to tt geometry on Frobenius manifolds. We give the main lines of the proof of the existence of a canonical tt structure on the base space of the universal unfolding of convenient and nondegenerate Laurent polynomials.

Unfoldings of Meromorphic Connections and a Construction of Frobenius Manifolds
The existence of universal unfoldings of certain germs of meromorphic connections is established. This is used to prove a general construction theorem for Frobenius manifolds. It includes semisimple Frobenius manifolds as a particular case. Another special case starts with variations of Hodge structures. This case is used to compare two constructions of Frobenius manifolds, the one in singulari...
متن کاملCharacterization of Deterministic and Probabilistic Sampling Patterns for Finite Completability of Low Tensor-Train Rank Tensor
In this paper, we analyze the fundamental conditions for low-rank tensor completion given the separation or tensor-train (TT) rank, i.e., ranks of unfoldings. We exploit the algebraic structure of the TT decomposition to obtain the deterministic necessary and sufficient conditions on the locations of the samples to ensure finite completability. Specifically, we propose an algebraic geometric an...
متن کاملNonsymmetric Askey-Wilson polynomials and Q-polynomial distance-regular graphs
In his famous theorem (1982), Douglas Leonard characterized the q-Racah polynomials and their relatives in the Askey scheme from the duality property of Q-polynomial distance-regular graphs. In this paper we consider a nonsymmetric (or Laurent) version of the q-Racah polynomials in the above situation. Let Γ denote a Q-polynomial distance-regular graph that contains a Delsarte clique C. Assume ...
متن کاملChern classes of tensor products
We prove explicit formulas for Chern classes of tensor products of vector bundles, with coefficients given by certain universal polynomials in the ranks of the two bundles.
متن کاملScaled Nuclear Norm Minimization for Low-Rank Tensor Completion
Minimizing the nuclear norm of a matrix has been shown to be very efficient in reconstructing a low-rank sampled matrix. Furthermore, minimizing the sum of nuclear norms of matricizations of a tensor has been shown to be very efficient in recovering a low-Tucker-rank sampled tensor. In this paper, we propose to recover a low-TT-rank sampled tensor by minimizing a weighted sum of nuclear norms o...
