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,
For example, the canonical map from a finite-dimensional vector space V to its second dual space is a canonical isomorphism; on the other hand, V is isomorphic to its dual space but not canonically in general. Isomorphisms are formalized using category theory. A morphism f: X â Y in a category is an isomorphism if it admits a two-sided inverse, meaning that there is another morphism g: Y â X in that category such that gf = 1X and fg = 1Y, where 1 X and 1 Y are the identity morphisms of X and Y, respectively.
