In solving mathematical equations, particularly linear simultaneous equations, differential equations and integral equations, the terminology homogeneous is often used for equations with some linear operator L on the LHS and 0 on the RHS. In contrast, an equation with a non-zero RHS is called inhomogeneous or non-homogeneous, as exemplified by ...
Cutting along a 1-sided manifold may make a non-orientable manifold orientable – such as cutting along an equator of the real projective plane – but may not, such as cutting along a 1-sided curve in a higher genus non-orientable surface, maybe the simplest example of this is seen when one cut a mobius band along its core curve.
This product turns Z[H \ G / H] into an associative ring whose identity element is the class of the trivial double coset [H]. In general, this ring is non-commutative. For example, if H = {1}, then the ring is the group algebra Z[G], and a group algebra is a commutative ring if and only if the underlying group is abelian.
In abstract algebra, a bimodule is an abelian group that is both a left and a right module, such that the left and right multiplications are compatible.Besides appearing naturally in many parts of mathematics, bimodules play a clarifying role, in the sense that many of the relationships between left and right modules become simpler when they are expressed in terms of bimodules.
This relationship between two-sided ideal extends to a relationship between the corresponding quotient rings: if is a two-sided ideal in that contains , and we write / for the corresponding ideal in / (i.e. / = ), the quotient rings / and (/) / (/) are naturally isomorphic via the (well-defined) mapping + (+) + / .
