Hepatocellular carcinoma is a cancer that starts in your liver. It's different from secondary liver cancers, which have spread to the liver from other organs. Although in most cases it can't be cured, treatment and support can help you live longer and better.
In the context of abstract algebra or universal algebra, a monomorphism is an injective homomorphism. A monomorphism from X to Y is often denoted with the notation X âª Y {\displaystyle X\hookrightarrow Y} . In the more general setting of category theory, a monomorphism (also called a monic morphism or a mono) is a left-cancellative morphism, that is, an arrow f : X â Y such that, for all morphisms g1, g2 : Z â X,
Group Homomorphism. A group homomorphism is a map between two groups such that the group operation is preserved: for all, where the product on the left-hand side is in and on the right-hand side in.As a result, a group homomorphism maps the identity element in to the identity element in : .ote that a homomorphism must preserve the inverse map because, so. In particular, the image of is a subgroup of and the group kernel, i.e., is a subgroup of. The kernel is actually a normal subgroup, as is the preimage of any normal subgroup of.
