Derivations of the subalgebras intermediate the general linear Lie algebra and the diagonal subalgebra over commutative rings
Let be an arbitrary commutative ring with identity, the general linear Lie algebra over , the diagonal subalgebra of . In case 2 is a unit of , all subalgebras of containing are determined and their derivations are given. In case 2 is not a unit partial results are given.

Extremal functions of the Nevanlinna-Pick problem and Douglas algebras
The Nevanlinna-Pick problem at the zeros of a Blaschke product B having a solution of norm smaller than one is studied. All its extremal solutions are invertible in the Douglas algebra D generated by B. If B is a finite product of sparse Blaschke products (Newman Blaschke products, Frostman Blaschke products) then so are all the extremal solutions. For a Blaschke product B a formula is given for the number C(B) such that if the NP-problem has a solution of norm smaller than C(B) then all its extremal...
