On noncontractible compacta with trivial homology and homotopy groups
, 2009 We construct an example of a Peano continuum $X$ such that: (i) $X$ is a one-point compactification of a polyhedron; (ii) $X$ is weakly homotopy equivalent to a point (i.e. $\pi_n(X)$ is trivial for all $n \geq 0$); (iii) $X$ is noncontractible; and (iv)

The dynamics of 1D Bloch electrons in constant electric fields
, 2004 We study the dynamics of a 1D Bloch electron subjected to a constant electric field. The periodic potential is supposed to be less singular than the $\delta $-like potential (Dirac comb). We give a rigorous proof of Ao's result \cite{Ao} that for a large

Second-order maximum principle controlled weakly singular Volterra integral equations [PDF]
Archives of Control SciencesThis work studies a class of singular Volterra integral equations that are (controlled) and can be applied to memory-related problems. For optimum controls, we prove a second-order Pontryagin type maximal principle.

Gronwall-Bellman Type Inequalities and Their Applications to Fractional Differential Equations
Abstract and Applied Analysis, 2013 Some new weakly singular integral inequalities of Gronwall-Bellman type are established, which can be used in the qualitative analysis of the solutions to certain fractional differential equations.
