New inequalities for the numerical radius of bounded linear operators defined on a complex Hilbert space $${\mathcal {H}}$$ are given. In particular, it is established that if T operator then $$\begin{aligned} w^2(T)\le \min _{0\le \alpha \le 1} \left\| T^*T +(1-\alpha )TT^* \right\| , \end{aligned}$$ where w(T) T. The obtained here non-trivial improvement well-known inequalities. As an applica...
We show that the bounded proper forcing axiom BPFA implies that there is a well-ordering of P(ω1) which is ∆1 definable with parameter a subset of ω1. Our proof shows that if BPFA holds then any inner model of the universe of sets that correctly computes א2 and also satisfies BPFA must contain all subsets of ω1. We show as applications how to build minimal models of BPFA and that BPFA implies t...
today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
