Про напівгрупу ін’єктивних ендоморфізмів напівгрупи $\mathbf{B}_\omega^{\it F_n}$, породжену сім’єю $\it F_n$ початкових скінченних інтервалів у $\omega$

 

Описано ін’єктивні ендоморфізми інверсної напівгрупи $\mathbf{B}_\omega^{\it F}$, яку введено в статті [3], у випадку коли сім’я $\it F_n$ породжена множиною {0,1,…,n} . Зокрема, показано, що напівгрупа ін’єктивних ендоморфізмів напівгрупи $\mathbf{B}_\omega^{\it F}$ є ізоморфною напівгрупі $(\omega, +)$. Також описано структуру напівгрупи $\it {End}(\it B_\lambda )$ усіх ендоморфізмів напівгрупи $\lambda \times \lambda$-матричних одиниць $\it B_\lambda $.
