Clifford approach to metric manifolds

Chisholm, J. S. R., Farwell, R. S. (1991)

Proceedings of the Winter School "Geometry and Physics"

[For the entire collection see Zbl 0742.00067.]For the purpose of providing a comprehensive model for the physical world, the authors set up the notion of a Clifford manifold which, as mentioned below, admits the usual tensor structure and at the same time a spin structure. One considers the spin space generated by a Clifford algebra, namely, the vector space spanned by an orthonormal basis { e j : j = 1 , ⋯ , n } satisfying the condition { e i , e j } ≡ e i e j = e j e i = 2 I η i j , where I denotes the unit scalar of the algebra and ( η i j ) the nonsingular Minkowski...

Co je dobrá matematika?

Pokroky matematiky, fyziky a astronomie

Článek přináší některé mé osobní myšlenky a názory na to, co je dobrá matematika, a zda bychom se měli snažit definovat tento pojem přesněji. Jako příklad je uveden příběh Szemerédiovy věty.

Towards a Digital Mathematics Library. Grand Bend, Ontario, Canada, July 8-9th, 2009

JSTOR is one of the primary providers of scholarly mathematics texts, providing access to journals in mathematics and the sciences dating back to the mid 1600’s. There is now a critical mass of literature online and the task going forward is as much to provide tools to make it more accurate, more discoverable and more usable as it is to add more material. Often the tool building can be done by collaboration between information retrieval experts and practitioners in the field, irrespective of the...
