(cf. {\tt \{ }, {\tt \} } in PostScript). |

However it makes the implementation of stack machines complicated. |

It is desirable that CMObject is independent of OX stack machine. |

Therefore we introduce an OpenMath like tree representation for CMO |

Tree object. |

This method allows us to implement tree structure easily |

on individual OpenXM systems. |

We treat polynomial rings and their elements as follows. |
|
|
|
Generic DMS ring is an $n$-variate polynomial ring $K[x_1, \ldots, x_n]$, |
|
where $K$ is a coefficient set. $K$ is unknown in advance |
|
and it is determined when coefficients of an element are received. |
|
When a server has received an element in Generic DMS ring, |
|
the server has to translate it into the corresponding local object |
|
on the server. Each server has its own translation scheme. |
|
In Asir such an element are translated into a distributed polynomial. |
|
In {\tt kan/sm1} things are complicated. |
|
{\tt kan/sm1} does not have any class corresponding to Generic DMS ring. |
|
{\tt kan/sm1} translates a DMS of N variables into an element of |
|
the CurrentRing. |
|
If the CurrentRing is $n'$-variate and $n' < n$, then |
|
an $n$-variate polynomial ring is newly created. |
|
|
|
|
|
If RingByName ({\tt CMO\_RING\_BY\_NAME}, yyy) |
|
is specified as the second field of DMS, |
|
it requests a sever to use a ring object whose name is yyy |
|
as the destination ring for the translation. |
