Barabanov- Stability
of
linear
third
order
differential inclusions I Abstract: For
irreducible
linear
differential
inclusions of order three the basic
concepts of Lyapunov exponent and extreme norm will be introduced and
explored to derive elegant necessary and sufficient conditions for
asymptotic stability. The relevant analytic and algebraic reformulation
of the problem will be presented and discussed.

for
global
asymptotic
stability of multilayered recurrent neural
networks(part I) Abstract:
The discrete-time multilayered Artificial Neural Networks with
local
feedback at each layer and a global feedback is considered. A special
state
space extension method is used to present corresponding equations in a
form
of automatic control system allowing use of criteria for absolute
stability
based on construction of local quadratic constraints (LQC). These LQC
and
corresponding linear matrix inequalities are presented and discussed.
The
case of system with biases in each neuron is also analyzed.

for
global
asymptotic
stability of multilayered recurrent neural
networks(part
II) Abstract:
The properties of special state space extension method will be
described. This method affects the local quadratic constraints, and
corresponding matrix inequalities will be derived. Finally, for
two-layered RNN a set of linear matrix inequalities will be presented
and analyzed.

Omotoyinbo- Absolute
stability
of
feedback
systems (part I) Abstract:
For the irreducible linear inclusions we consider properties of
Lyapunov exponent and corresponding extreme norms. A numerical
algorithm to compute the Lyapunov exponent for discrete time linear
inclusions will be presented and discussed.

Omotoyinbo- Absolute
stability
of
feedback
systems (part III) Abstract: We
consider dual linear inclusions in connection with behavior of
gradients of extreme norms along the worst case solutions. A
property similar to the Pontryagin maximum principle for the case of
linear inclusions will be presented and discussed.

Abdullayev- Optimal
Lipschitz
Extensions and Partial Differential Equations
(part I) Abstract:
Motivated by the problem of finding optimal Lipschitz
extensions of maps defined on the boundary of an N-dimensional domain,
we introduce Aronsson's notion of absolutely minimizing Lipschitz
extensions (AMLE) and we discuss its relationship with viscosity
solutions of the infinity-Laplace equation.
