the Markov chain with this transition intensity matrix is ergodic. To explain our method with more details, notice that (1.1) guarantees the absolute continuity of the distribution for (t)-Markov chain with respect to the distribution for-Markov chain. It is also assumed that -Markov chain is ergodic but the geometrical ergodicity is not required.

The Transit 2008-03-01 For a time homogeneous process, P(s, t) = P( t - s) and Q(t) = Q for all t 3 0. The long-run properties of continuous-time, homogeneous Markov chains are often studied in terms of their intensity matrices. One technique was introduced by process, the infinitesimal intensity of a jump from state ei to ej with one (resp. no) arrival. More-over, D0+D1 is the intensity matrix of the (homogeneous) Markov process {Xt}t≥0.

Details. For a continuous-time homogeneous Markov process with transition intensity matrix Q, the probability of occupying state s at time u + t conditionally on occupying state r at time u is given by the (r,s) entry of the matrix P(t) = exp(tQ), where exp() is the matrix exponential.

Moreover nullity(A I n) = 1. PROOF Suppose j j= 1;AX= X;X2V n(C);X6= 0. Then inequalities (15) and (16) reduce to jx kj= Xn where t(0) =0 and 0< t(1) <…< t(K) ≤ t are the jump times of G and. ∏ G ( t ( k)) = G ( t ( k)) − G ( t ( k − 1)) Define. α n n ( t) = − ∑ j ≠ h α h j ( t) and the intensity matrix function.

Markov processes • Stochastic process – p i (t)=P(X(t)=i) • The process is a Markov process if the future of the process depends on the current state only - Markov property – P(X(t n+1)=j | X(t n)=i, X(t n-1)=l, …, X(t 0)=m) = P(X(t n+1)=j | X(t n)=i) – Homogeneous Markov process: the probability of state change is unchanged In Markov process, transition intensities from state i to j are defined as derivatives of transition probabilities at zero: $$q_{ij}=p_{ij}'(0)$$ However I can't somehow catch the interpretation of transition intensities. A continuous-time Markov chain is a continuous stochastic process in which, for each state, the process will change state according to an exponential random variable and then move to a different state as specified by the probabilities of a stochastic matrix.
