Extensions of tensors that maintain the rank
In the theory of the ranks of tensors, one line of research consists in generalising basic properties of the rank of matrices to appropriate statements that often require significant reformulation. This talk will focus on extensions of tensors that maintain the rank of the original tensor - for various rank notions - and on how constrained or flexible these extensions are. We will take as our starting point the answer that this question has for matrices, and discuss several potential generalisations: some that we will show to be true, some that we will show to be false in a major way, and finally some that we will view as conjectures and which have strong connections to several existing questions on the ranks of tensors that we will finish by describing.

A “Periodicity” Phenomenon of the Attaching Map of the Two-Cell Complex
In this talk, I would like to introduce our recent work on the “Periodicity” phenomenon of the attaching map of the suspended two-cell CW complex.I will introduce Selick-Wu's A^{min}-theory, a theory on the homotopy functor decomposition and becoming a bridge between homotopy theory and the representation theory. Employing this theory, we deduce that the attaching map of the CW complex above manifests a“periodicity”phenomenon.The result essentially furnishes, up to the present, one of the most effective methods for computing the 2-torsion parts of the unstable homotopy groups \pi_{i}(\Sigma(S^{n} \cup e^{n+k+1})), where 3n + 2k + 1 < i <4n + 3k + 3 and n>1, provided the requisite homotopy groups of spheres are known.The proof requires the Hopf algbra structure of the looped homotopy fibre of the pinch map, giving a generalization of a result of Cohen-Moore-Neisendorfer’s 1979 classic paper.

Various ways to obtain a polynomial equation with one catalytic variable
In combinatorial literatures, discrete difference equations are always called polynomial equation with one catalytic variable. Under some mild conditions, it is possible to find a unique formal series solution. The solving strategy was first proposed in 2006 by MIREILLE BOUSQUET-M?LOU and many problems was solved in this framework.In this talk， I would like to introduce different ways to achieve a polynomial equation with one catalytic variable. I will introduce the ideas without the giving full proofs. I pick examples from different literatures by MIREILLE BOUSQUET-M?LOU, ANDREW ELVEY PRICE, Kilian Raschel and also my recent work. The examples incudes lattice walks in different domains and some graph enumeration problems.

Eigenvalue Problems of Hormander Operators on Non-equiregular sub-Riemannian Manifolds
Let $\Omega$ be a bounded connected open subset in \mathbb{R}^n$with smooth boundary $\partial\Omega$. Suppose that we have asystem of real smooth vector fields $X=(X_{1},X_{2},$$\cdots,X_{m})$ defined on a neighborhood of $\overline{\Omega}$that satisfies the H\"{o}rmander's condition. For a self-adjoint sub-elliptic operator $\triangle_{X}=-\sum_{i=1}^{m}X_{i}^{*} X_i$ on $\Omega$, we denote its $k^{th}$ Dirichlet eigenvalue by $\lambda_k$. We will provide an uniform upper bound for the sub-elliptic Dirichlet heat kernel and also give an explicit sharp lower bound estimate for $\lambda_{k}$,which has a polynomially growth in $k$ of the order related to the non-isotropical dimension. We will establish an explicit asymptotic formula (Weyl law) of $\lambda_{k}$ that generalizes the M\'{e}tivier's results in 1976. Our asymptotic formula shows that under a certain condition, our lower bound estimate for $\lambda_{k}$ is optimal in terms of the growth of $k$. Moreover, the upper bound estimate of the Dirichlet eigenvalues for sub-elliptic operators will also be given, which, in a certain sense, has the optimal growth order.
