In mathematics , a function is locally bounded if it is bounded around every point. A family of functions is locally bounded if for any point in their domain all the functions are bounded around that point and by the same number.

In algebraic geometry , local cohomology is an algebraic analogue of relative cohomology . Alexander Grothendieck introduced it in seminars in Harvard in 1961 written up by Hartshorne (1967) , and in 1961-2 at IHES written up as SGA2 - Grothendieck (1968) , republished as Grothendieck (2005) . Given a function (more ge... | https://en.wikipedia.org/wiki/Local_cohomology |
Local coordinates are the ones used in a local coordinate system or a local coordinate space . Simple examples:
Local systems exist for convenience. On ancient times, every work was made on relative bases as there was no conception of global systems. Practically, it is better to use local systems for small works as ho... | https://en.wikipedia.org/wiki/Local_coordinates |
Local elevation is a technique used in computational chemistry or physics , mainly in the field of molecular simulation (including molecular dynamics ( MD ) and Monte Carlo ( MC ) simulations). It was developed in 1994 by Huber, Torda and van Gunsteren [ 1 ] to enhance the searching of conformational space in molecula... | https://en.wikipedia.org/wiki/Local_elevation |
In topology , a branch of mathematics , local flatness is a smoothness condition that can be imposed on topological submanifolds . In the category of topological manifolds, locally flat submanifolds play a role similar to that of embedded submanifolds in the category of smooth manifolds . Violations of local flatness d... | https://en.wikipedia.org/wiki/Local_flatness |
Local food is food that is produced within a short distance of where it is consumed, often accompanied by a social structure and supply chain different from the large-scale supermarket system . [ 1 ]
Local food (or locavore ) movements aim to connect food producers and consumers in the same geographic region, to devel... | https://en.wikipedia.org/wiki/Local_food |
Local hormones are a large group of signaling molecules that do not circulate within the blood. Local hormones are produced by nerve and gland cells and bind to either neighboring cells or the same type of cell that produced them. Local hormones are activated and inactivated quickly. [ 1 ] They are released during phys... | https://en.wikipedia.org/wiki/Local_hormone |
A local information system ( LIS ) is a form of information system built with business intelligence tools , designed primarily to support geographic reporting . They overlap with some capabilities of geographic information systems (GIS), although their primary function is the reporting of statistical data rather than t... | https://en.wikipedia.org/wiki/Local_information_systems |
The murine local lymph node assay (LLNA) is an in vivo test for skin sensitisation .
LLNA has largely superseded the guinea pig maximisation test and the Buehler test . It is considered more scientific and less cruel (lower number of animals; less suffering) and has found broad scientific and regulatory acceptance.
