In linear algebra the term "linear operator" most commonly refers to linear maps (i.e., functions preserving vector addition and scalar multiplication) that have the added peculiarity of mapping a vector space into itself (i.e., ). The term may be used with a different meaning in other ...
Hence, we can make definitions for continuous operators similar to their counterparts in linear algebra, including the following key classes of bilinear operators: • Self-adjoint: We call a bilinear form self-adjoint if ∀u, v : a(u, v) = a(v, u). This generalizes the definition ...

This section introduces the decomposition of V as the direct sum of the generalized eigenspaces for a general operator. By using this decomposition, we can write every general operator in the form o…
Therefore (t+b-a) is invertible and -t\notin \sigma(b-a) .This implies \sigma(b-a)\in \mathbb R^+ .Let H be a vector space. \sigma:H^2\to \mathbb C is called sesquilinear form if \sigma(\lambda x+y,z)=\lambda \sigma(x,z)+\sigma(y,z) and \sigma( x,\lambda y+...

≠ L̂2L̂1The algebra of operators differs in this regard from the ordinary algebra of numbers. The possibility of changing the order of the factors in the product of two operators is closely connected with the possibility of the simultaneous measurement of the physical quantities to which ...
Since the conditions (2.1),(2.2) are linear, the Lax operators constitute an associative algebra, hence the corresponding Lie algebra. The latter is called Lax operator algebra. If the function L, besides (2.1)—(2.3), satisfies the condition tr L = 0, it is called an sl(n)-valued...
