unitáris
Unitáris is a term that can refer to several related concepts, primarily within mathematics and linguistics. In mathematics, a unitáris transformation is a type of linear transformation on a complex vector space. This transformation preserves the inner product, which is a fundamental operation defining distances and angles in the space. Mathematically, a transformation U is unitáris if U*U = UU* = I, where U* is the conjugate transpose of U, and I is the identity matrix. Unitáris transformations are crucial in quantum mechanics and signal processing, where they represent operations that conserve probability or energy.
In linguistics, "unitáris" describes a grammatical structure or a word that functions as a single, indivisible
