We find an expression for Gateaux derivative of the C∗ -algebra norm. This gives us alternative proofs or generalizations of various known results on the closely related notions of subdifferential sets, smooth points and Birkhoff-James orthogonality for spaces B(H) and Cb(Ω). We also obtain an expression for subdifferential sets of the norm.

This notion of derivative is a generalization of the ordinary derivative of a function on the real numbers since the linear maps from to are just multiplication by a real number. In this case, is the function Properties A function differentiable at a point is continuous at that point.

An operator (or induced) matrix norm is a norm jj:jj a;b: Rm n!R de ned as jjAjj a;b=max x jjAxjj a s.t. jjxjj b 1; where jj:jj a is a vector norm on Rm and jj:jj b is a vector norm on Rn. Notation: When the same vector norm is used in both spaces, we write.

The derivative of a vector-valued function can be understood to be an instantaneous rate of change as well; for example, when the function represents the position of an object at a given point in time, the derivative represents its velocity at that same point in time. We now demonstrate taking the derivative of a vector-valued function.

Subject classifications. Let X and Y be Banach spaces and let f:X->Y be a function between them. f is said to be Gâteaux differentiable if there exists an operator T_x:X->Y such that, for all v in X, lim_ (t->0) (f (x+tv)-f (x))/t=T_xv. (1) The operator T_x is called the Gâteaux derivative of f at x. T_x is sometimes assumed to be bounded.

The Gateaux derivative of k · k at vin direction of uis defined as lim t→0 kv+tuk −kvk t. We say k · k is Gateaux differentiable at 0 6= vif and only if for all u∈ V, lim t→0 kv+tuk−kvk t exists. A concept related to the Gateaux derivative of norm function is the subdifferential set of norm function (see [9]). The subdifferential set

The concept of logarithmic derivative μ [ A] is used in [2], [1] in the theory of ordinary differential equations to obtain new results, e.g., in stability problems, and the results improve those obtained by using the norm ∥ A ∥.

This norm can be defined as the square root of the inner product of a vector with itself. A seminorm satisfies the first two properties of a norm, but may be zero for vectors other than the origin. [1] A vector space with a specified norm is called a normed vector space.
