On a class of nonlinear variational inequalities: High concentration of the graph of weak solution via its fractional dimension and Minkowski content

open access: yesElectronic Journal of Differential Equations, 2007
Weak continuous bounded solutions of a class of nonlinear variational inequalities associated to one-dimensional p-Laplacian are studied. It is shown that a kind of boundary behaviour of nonlinearity in the main problem produces a kind of high boundary ...

The Power of Poincar\'e: Elucidating the Hidden Symmetries in Focal Conic Domains

open access: yes, 2010
Focal conic domains are typically the "smoking gun" by which smectic liquid crystalline phases are identified. The geometry of the equally-spaced smectic layers is highly generic but, at the same time, difficult to work with. In this Letter we develop an

Characterizing neuromorphologic alterations with additive shape functionals

open access: yes, 2004
The complexity of a neuronal cell shape is known to be related to its function. Specifically, among other indicators, a decreased complexity in the dendritic trees of cortical pyramidal neurons has been associated with mental retardation.

Complex dimensions of fractals and meromorphic extensions of fractal zeta functions

open access: yes, 2017
We study meromorphic extensions of distance and tube zeta functions, as well as of geometric zeta functions of fractal strings. The distance zeta function $\zeta_A(s):=\int_{A_\delta} d(x,A)^{s-N}\mathrm{d}x$, where $\delta>0$ is fixed and $d(x,A ...

On the Potential of the Excluded Volume and Auto-Correlation as Neuromorphometric Descriptors

open access: yes, 2005
This work investigates at what degree two neuromorphometric measurements, namely the autocorrelation and the excluded volume of a neuronal cell can influence the characterization and classification of such a type of cells.

Box-counting dimension of solution curves for a class of two-dimensional nonautonomous linear differential systems [PDF]

open access: yes, 2017
A class of two-dimensional linear differential systems is considered. The box-counting dimension of the graphs of solution curves is calculated.
