    Two teams of undergraduates participated in the Mathematical Contest in Modeling. The team of Andrew Harris, Dante Iozzo, and Nigel Michki was designated as "Meritorious Winner" (top 9%) and the team of George Braun, Collin Olander, and Jonathan Tang received honorable mention (top 31%). John Ringland served as the faculty advisor to both teams.

"The book is about sub-Laplacians on stratified Lie groups. The authors present the material using an elementary approach. They achieve the level of current research starting from the basic notions of differential geometry and Lie group theory.

It is known that the standard second order Riesz transforms corresponding to H are generally unbounded in L p (G). In this paper, we establish boundedness in L p for modified second order Riesz transforms, which are defined using derivatives on a nilpotent group.

The drift term arises from the non-symmetry of the random walk and it vanishes when the random walk is symmetric.

Kac has introduced the notion of (polynomial) growth for a graded Lie algebra. Here we consider Lie algebras L that occur as ideals either in the rational homotopy Lie algebra of a simply connected CW complex of finite type and finite category or as ideals in the homotopy Lie algebra of a local noetherian ring.

Gebiete heat equation on a wide class of left-invariant sub-Riemannian structures on Lie groups. We then apply this method to the most important 3D Lie groups: SU(2), SO(3), and SL(2) with the metric defined by the Killing form, the Heisenberg group H2, and the group of rototranslations of the plane SE(2).

The category of papers on pseudo-differential operators contains such topics as elliptic operators assigned to diffeomorphisms of smooth manifolds, analysis on singular manifolds with edges, heat kernels and Green functions of sub-Laplacians on the Heisenberg group and Lie groups with more complexities than but closely related to the Heisenberg.

Polynomial division mc-TY-polydiv In order to simplify certain sorts of algebraic fraction we need a process known as polynomial division. This unit describes this process. In order to master the techniques explained here it is vital that you undertake plenty of practice exercises so that all this becomes second nature.

Lie groups: On Lie groups one can choose $\mu$ to be any left-invariant measure (any such a measure differs up to a constant rescaling, which does not change the divergence and thus the sub-Laplacian). Moreover it is natural to choose a left-invariant distribution $\mathcal{D}$.

is singular. We then move to left-invariant sub-Riemannian structures on Lie groups and we show that a Lie group is unimodular if and only if the invariant hypoelliptic Laplacian is the sum of squares. We also provide an example of a 3D non-unimodular Lie group for which the invariant hypoelliptic Laplacian is not the sum of squares.

Long and synthetic division are two ways to divide one polynomial (the dividend) by another polynomial (the divisor).

These methods are useful when both polynomials contain more than one term, such as the following two-term polynomial: 2+ 3. This handout will discuss the rules and processes for dividing polynomials using these methods.

For example every connected nilpotent Lie group has polynomial volume growth. On connected Lie groups of polynomial growth, associated with the sublapla- n 2 cian Δ = X and corresponding heat kernel, Poincar´ e inequalities also hold j=1 j (see [21, 19]). The heat kernel satisfies the Gaussian upper estimate (G) (see [22, Theorem VIII]).

And like always, pause this video and see if you could have a go at it. so let's remind ourselves what a Maclaurin polynomial is, a Maclaurin polynomial is just a Taylor polynomial centered at zero, so the form of this second degree Maclaurin polynomial, and we just have to find this Maclaurin expansion until our second degree term, it's going.Finally, for any of the groups H above, we may consider the group J(H) obtained by including the matrix J = 0 I-I 0.

Not all of these groups yields distinct distributions, but 24 of them do. There is also an index 2 subgroup K of J(G 2 G 2).
