A Cornucopia of Carnot Groups in Low Dimensions [PDF]
Stratified groups are those simply connected Lie groups whose Lie algebras admit a derivation for which the eigenspace with eigenvalue 1 is Lie generating.

Sharp measure contraction property for generalized H-type Carnot groups [PDF]
We prove that H-type Carnot groups of rank $k$ and dimension $n$ satisfy the $\mathrm{MCP}(K,N)$ if and only if $K\leq 0$ and $N \geq k+3(n-k)$. The latter integer coincides with the geodesic dimension of the Carnot group.

Hardy-Type Inequalities for the Carnot–Carathéodory Distance in the Heisenberg Group [PDF]
In this paper we study Hardy inequalities in the Heisenberg group $${\mathbb {H}}^n$$ H n , with respect to the Carnot–Carathéodory distance $$\delta $$ δ from the origin.

Review of Carnot Battery Technology Commercial Development
Carnot batteries are a quickly developing group of technologies for medium and long duration electricity storage. It covers a large range of concepts which share processes of a conversion of power to heat, thermal energy storage (i.e., storing thermal ...

Jean-Marie Souriau’s Symplectic Foliation Model of Sadi Carnot’s Thermodynamics [PDF]
The explanation of thermodynamics through geometric models was initiated by seminal figures such as Carnot, Gibbs, Duhem, Reeb, and Carathéodory. Only recently, however, has the symplectic foliation model, introduced within the domain of geometric ...

Attainable Set for Rank 3 Step 2 Free Carnot Group with Positive Controls [PDF]
We find the attainable set for a control system on the free Carnot group of rank 3 and step 2 with positive controls. This kind of control systems is connected with the theory of free Lie semigroups; with some estimates for probabilities of inequalities ...

For some class of 2-step Carnot groups $ D_n $ with 1-dimensional centre we find the exact values of the constants in $ (1, q_2) $-generalized triangle inequality for their $ \text{Box} $-quasimetrics $ \rho_{\text{Box}_{D_n}} $. Using this result we get

Hilbert-Haar coordinates and Miranda's theorem in Lie groups
We study the interior regularity of solutions to a class of quasilinear equations of non-degenerate p-Laplacian type on Lie groups that admit a system of Hilbert-Haar coordinates. These are coordinates with respect to which every linear function has zero

Nature and importance of follicular lymphoma precursors
It is now widely recognized that cancer development is a protracted process requiring the stepwise acquisition of multiple oncogenic events. In humans, this process can take decades, if not a lifetime, blurring the notion of ‘healthy’ individuals ...
