Long-time uniform stability of solution to magnetohydrodynamics equation
      
The long-time uniform stability of solutions to the initial value problems for 2-dimen sional Magnetohydrodynamics equations is studied.
      
The survival probability in finite time period in fully discrete risk model
      
The probabilities of the following events are first discussed in this paper: the insurance company survives to any fixed time k and the surplus at time k equals x≥1.
      
At the same time, a necessary and sufficient condition for the equality of the spectrum of Q(G) and L(G) is given.
      
The robust stability for some types of time-varying interval matrices and nonlinear time-varying interval matrices is considered and some sufficient conditions for robust stability of such interval matrices are given.
      
Discrete-time stochastic equilibrium with infinite horizon incomplete asset markets
      
This paper examines the existence of general equilibrium in a discrete time economy with the infinite horizon incomplete markets.
      
Optimal L2 and H1 estimates for the error and its time derivative are established.
      
In this paper, the global and local linear independence of any compactly supported distributions by using time domain spaces, and of refinable vectors by invariant linear spaces are investigated.
      
Further discussion on statistical properties of activity flow time in pert
      
In this paper attempts are made at answering the problems on the statistical properties of activity flow time in PERT raised by the late famous mathematican Hua Loo-keng.
      
Persistence and stability in a ratio-dependent food-chain system with time delays
      
The global existence and finite time blow up of the positive solution for a nonlinear degenerate parabolic equation with non-local source are studied.
      
Some results on lag increments of principal value of brownian local time
      
Let W be a standard Brownian motion, and define Y(t)=∫0tds/W(s) as Cauchy's principal value related to the local time of W.
      
MKP (B,S,m,n) is strongly NP-Complete and no polynomial-time approximation algorithm can have an approximation ratio better than 0.5.
      
In the case where a graph is not w-balanced, a polynomial-time algorithm to find a subgraph of maximum w-density is proposed.
      
Under appropriate hypotheses, the global existence and blow-up in finite time of positve solutions are obtained.
