Subfields

Some articles on subfields, subfield:

Artificial Intelligence
... and specialized, deeply divided into subfields that often fail to communicate with each other ... Some of the division is due to social and cultural factors subfields have grown up around particular institutions and the work of individual researchers ... There are subfields which are focused on the solution of specific problems, on one of several possible approaches, on the use of widely differing tools and towards the accomplishment of ...
Tensor Product Of Fields - Compositum of Fields
... where such a common over-field is easy to identify (for example if K and L are both subfields of the complex numbers) or one proves a result that allows one ... Subfields K and L of M are linearly disjoint (over a subfield N) when in this way the natural N-linear map of to K.L is injective ... the nth roots of unity, for n a composite number, the subfields generated by the pkth roots of unity for prime powers dividing n are linearly disjoint for distinct p ...
DNA Nanotechnology - Fundamental Concepts - Subfields
... sometimes divided into two overlapping subfields structural DNA nanotechnology and dynamic DNA nanotechnology ... devices, combine features of both the structural and dynamic subfields ...
Composite Field (mathematics)
... Let L be a field, and let F, K be subfields of L ... the (internal) composite of F and K is defined to be the intersection of all subfields of L containing both F and K ... When F and K are not regarded as subfields of a common field then the (external) composite is defined using the tensor product of fields ...
