Homological transcendence degree
Let D be a division algebra over a base field k. The homological transcendence degree of D, denoted by HtrD, is defined to be the injective dimension of the algebra D⊗k D ◦. We show that Htr has several useful properties which the classical transcendence degree has. We extend some results of Resco, Rosenberg, Schofield and Stafford, and compute Htr for several classes of division algebras. The ...
متن کاملFiltrations on Chow Groups and Transcendence Degree
For a smooth complex projective variety X defined over a number field, we have filtrations on the Chow groups depending on the choice of realizations. If the realization consists of mixed Hodge structure without any additional structure, we can show that the obtained filtration coincides with the filtration of Green and Griffiths, assuming the Hodge conjecture. In the case the realizations cont...
متن کاملConjectures for large transcendence degree
We state two conjectures, which together would yield strong results of algebraic independence related to Schanuel’s Conjecture. Partial results on these conjectures are also discussed. 1991 Mathematics Subject Classification: 11J82, 11J85.

متن کاملCycles over Fields of Transcendence Degree One
We extend earlier examples provided by Schoen, Nori and Bloch to show that when a surface has the property that the kernel of its Albanese map is non-zero over the field of complex numbers, this kernel is non-zero over a field of transcendence degree one. This says that the conjecture of Bloch and Beilinson that this kernel is zero for varieties over number fields is precise in the sense that i...
