What is Direct image with compact support?

In mathematics compact convergence is a type of convergence that generalizes the idea of uniform convergence. It is associated with the compact-open topology.

In algebra, a locally compact field is a topological field whose topology forms a locally compact Hausdorff space. These kinds of fields were originally introduced in p-adic analysis since the...

In mathematics, a Hecke algebra of a locally compact group is an algebra of bi-invariant measures under convolution.

In mathematics, algebraically compact modules, also called pure-injective modules, are modules that have a certain "nice" property which allows the solution of infinite systems of equations in the module by...

In mathematics, a maximal compact subgroup K of a topological group G is a subgroup K that is a compact space, in the subspace topology, and maximal amongst such subgroups....

In mathematics and theoretical physics, a locally compact quantum group is a relatively new C*-algebraic approach toward quantum groups that generalizes the Kac algebra, compact-quantum-group and Hopf-algebra approaches. Earlier attempts...

In functional analysis, compact operators are linear operators on Banach spaces that map bounded sets to relatively compact sets. In the case of a Hilbert space H, the compact operators...

In mathematics a topological space is called countably compact if every countable open cover has a finite subcover.

In mathematics, in the field of sheaf theory and especially in algebraic geometry, the direct image functor generalizes the notion of a global section functor to the relative case. Given...

In mathematics, cohomology with compact support refers to certain cohomology theories, usually with some condition requiring that cocycles should have compact support.
