I like quantum groups, representation theory, noncommutative algebra, and homological algebra, mainly in the context of noncommutative geometry.

Norms on Clifford algebra (C^* norm)
Well, the map you mention is an isomorphism of $\ast$-algebras, and matrix algebras (and direct sums of matrix algebras) have a unique C$^\ast$-norm (the operator norm). Perhaps there is some way to interpret this norm intrinsically on the Clifford algebra; perhaps consider the operator norm of the Clifford algebra acting on itself by left multiplication. |

How to recognize a Hopf algebra?
For the sake of those reading this question (including me!), could you specify the sense in which you mean "regular"? It's a pretty overloaded term... |

Software for noncommutative Groebner bases over rational function fields
I've seen that other question, but it didn't address the question of which base fields are allowed. |

Software for noncommutative Groebner bases over rational function fields
@NeilHoffman, that seems to be for commutative rings. I did find this: magma.maths.usyd.edu.au/magma/handbook/text/900#9876 which indicates that Magma can do Groebner basis calculations for noncommutative algebras, but it doesn't say much about what coefficient fields are possible. |

Basis of a Finite Dimensional Algebra with a Finitely Generated Relation Set By Computer
@Leandro, do you know if there is a way to do this sort of thing in GAP when the algebra is defined over a field of rational functions? |

What is a complex inner product space “really”?
I think it's important to note what translating the concept of "normal operator" to the complex setting yields. The point is that any operator can be decomposed into real and imaginary parts, which are self-adjoint and hence diagonalizable. It's easy to check that an operator is normal if and only if its real and imaginary parts commute, so that they are simultaneously diagonalizable. |
