The phrase "a unique and stable" is correct and usable in written English.
It can be used to describe something that is both distinctive and consistent in nature or quality.
Example: "The research team developed a unique and stable solution to the problem that had been affecting the industry for years."
Alternatives: "a distinctive and reliable" or "an exclusive and consistent".
Moreover, we prove that the obtained system has a unique and stable limit cycle and it corresponds to the desired limit cycle trajectory.
DNA is replicated in a defined temporal order that is developmentally regulated and constitutes a unique and stable fingerprint of a given cell type.
Hydraulics laws show that in the right conditions there may be a unique and stable relationship between stage and discharge, which can be described by a rating curve.
If (K>K_{2}), a unique and stable limit cycle bifurcates from the equilibrium (E^) via the Hopf bifurcation.
For system (3.1), if (q^{2}+mq-n-1=0) holds, then (a(0)< 0 ) (respectively >0) implies that a unique and stable (respectively unstable) closed invariant curve bifurcates from (X^), and the Neimark-Sacker bifurcation in (X^) is supercritical (respectively subcritical).
end{aligned} The first Lyapunov coefficient is begin{aligned} l(K &=frac{1}{2omega^{2}}Re(ig_{20}g_{11}+ omega g_{21}) &=frac{omegatilde{d}^{2}}{2omega^{2}}(ca_{20}+a_{30}) &< 0. end{aligned} Therefore, a unique and stable limit cycle bifurcates from the equilibrium (E^) via the Hopf bifurcation for (K>K_{2}).
Clearly, one would like to think of the Walrasian equilibrium as an unique and stable steady-state of the model, and the economy would reach in the long run.
Polybenzimidazole (PBI) is a unique and highly stable linear heterocyclic polymer.
This eliminates many non-physical solutions and leads to a unique and globally stable uniform state in the limit of very small or large residence time.
The implicit numerical system defined by the linear difference equation in (35) has a unique and unconditionally stable solution.
and bound.2., the dynamic is very simple: it is characterized by a unique and asymptotically stable stationary state, V f = 0.
