suspension

1. (chemistry, physics) The state of a solid or substance produced when its particles are mixed with, but not dissolved in, a fluid, and are capable of separation by straining.Examples: "As the solids clump together, they get heavier causing them to fall out of suspension in the water."countableuncountable

2. (education) The process of barring a student from school grounds as a form of punishment (particularly out-of-school suspension).Examples: "suspension from school as a disciplinary measure"; "[…] Donna Thomas, John Tiedeman, David Jones, and Richard Williams, all students in the Granville Junior-Senior High School, conceived a plan in November 1978 to produce a satirical publication addressed to the school community. […] [Assistant Principal Frederick] Reed summoned Tiedeman and discussed with him the “dangers” of publishing material that might offend or hurt others. Specifically, he told Tiedeman that a similar publication several years before had culminated in the suspension of the students involved."countableuncountable

3. (music) The act of or discord produced by prolonging one or more tones of a chord into the chord which follows, thus producing a momentary discord, suspending the concord which the ear expects.Examples: "As in Sequenza IV, the suspension of the chord creates several different layers of activity, which can be understood by looking at the right hand’s chord in bar two."countableuncountable

4. (Scots law) A stay or postponement of the execution of a sentence, usually by letters of suspension granted on application to the Lord Ordinary.countableuncountable

5. (topology) A topological space derived from another by taking the product of the original space with an interval and collapsing each end of the product to a point.Examples: "To get an intuitive feeling for the characteristics of H'-spaces, it is instructive to consider an important class of such spaces, the suspensions. The suspension of an arbitrary topological space Y is defined to be the quotient space of Y#92;timesI where Y#92;times 0 is identified to one point and Y#92;times 1 is identified to another point. For example, the suspension of a circle is a cylinder with the two ends collapsed into one point each; in other words, a space homeomorphic to a sphere."countableuncountable

6. (topology) A function derived, in a standard way, from another, such that the instant function’s domain and codomain are suspensions of the original function’s.Examples: "A model category is called pointed if the initial object and terminal object are the same. The homotopy category of any pointed model category acquires a suspension functor denoted by #92;Sigma. It turns out that #92;text#123;Ho#125;(M) is a pre-triangulated category in a natural way[…]. When the suspension is an equivalence, M is called a stable model category, and in this case #92;text#123;Ho#125;(M) becomes a triangulated category[…]."countableuncountable
