The frame usually incorporates an accordion-style truss which folds up compactly. Conversely, every compactly generated Hausdorff space is a quotient of some locally compact Hausdorff space. Therefore, the LTCC can be arranged more compactly and less expensively. Algebraic topologists work with compactly generated spaces, CW complexes, or spectra. The Boston Terrier is a compactly built, well-proportioned dog. Examples of topological spaces that fail to be compactly generated include the following. The space of continuous and compactly supported functions is dense in . The linear space of compactly supported distributions does, however, admit an identity under the convolution. These cases allowed type to be compactly transported. Using tensor notation, we can write all this more compactly. Video compression algorithms attempt to reduce redundancy and store information more compactly. Horned puffins fly compactly and quickly, above sea level. Consequently, they convey information more compactly than normal vernacular speech or writing. Assume the same hypotheses as before, and let be a compactly supported -form on . This could be represented compactly by the string .
