We show that Jordan multiplicative bijective maps on prime operator algebrasmust be additive. As its application, we show that every Jordan * multiplicative bijec-tive map on every factor C~* algebra is a C~* isomorphism or a conjugate C~* isomorphism,in the special case of B, it must be a *-isomorphism or a conjugate *-isomorphism.We also prove the additivity of Jordan multiplicative bijective maps on nest algebras.

It is proved that the least squareestimators of linear estimable functions of regression coefficients areadmissible under matrix loss and minimax. The necessary and sufficientexistence conditions are derived for the uniformly minimum riskequivariant estimators of linear estimable functions ofregression coefficients under an affine group and a transitive group oftransformations respectively. It is also proved that there are no UMREestimators ofthe covariance matrix and variance under an affine groupof transformations and quadratic loss functions.

At present time thesemaps have become important objectors and tools in studying operator algebras. Nestalgebras is a class of most importaut non-semisimple, non-prime and non-self adjointoperator algebras. Their finite dimensional models are upper triangular matrix algebras,but the infinite dimensional models are more complex.

Indeed, it was not much in my Thoughts, that we could be able to recover the Ship; but my View was that if they went away without the Boat, I did not much question to make her fit again, to carry us away to the Leeward Islands, and call upon our Friends, the Spaniards, in my Way, for I had them still in my Thoughts.

说实话，我认为收复大船的把握不大。我的看法是，只要他们不把那只小船弄走，我们就可以把它重新修好。那样，我们就可乘它去利华德群岛，顺便把那些西班牙朋友也可带走。因为我心里还时刻记着他们。
