Via the specified research of the trendy improvement of the mechanics of deformable media are available the deep inner contradiction. From the single hand it truly is declared that the deformation and fracture are the hierarchical tactics that are associated and unite a number of structural and scale degrees. From the opposite hand the sequential research of the hierarchy of the deformation and destruction isn't really conducted.

Example text

In a normed vector space X is said to be completet fi its linear span is dense in X , that is, if for each vector x and each E > 0 there is a finite linear combination c 1x, + ’ . cnx, such that + IIX - (C’XI + . . + c,xn)II < E. It is a direct and important consequence of the Hahn-Banach theorem that the completeness of a sequence of vectors {x,} in X is equivalent to the following condition : if p E X * (the topological dual of X ) and if p ( x , ) = 0 ( n = 1,2,3,. ), then p = 0. When X is a Hilbert space, the Riesz representation theorem shows that all is well-the former definition (see Section 3) agrees with the present one.

D) Show that { f,,} is a Hilbert basis if and only if there exists a constant B > 0 such that for arbitrary scalars c l , . , c, (n = 1 , 2 , 3 , . ). Let { j ; , }be a basis for a Hilbert space H and let {g,} be its biorthogonal basis. } are equivalent if and only if { J n }is a Riesz basis. 6. Let { j i I }be a basis for a Hilbert space H and let g, = A,f,, where 5. Prove or disprove: 9 {fn} and {g,,} are equivalent. The Stability of Bases in Banach Spaces Two mathematical objects that are in some sense “close” to each other often share common properties.

C,xn)II < E. It is a direct and important consequence of the Hahn-Banach theorem that the completeness of a sequence of vectors {x,} in X is equivalent to the following condition : if p E X * (the topological dual of X ) and if p ( x , ) = 0 ( n = 1,2,3,. ), then p = 0. When X is a Hilbert space, the Riesz representation theorem shows that all is well-the former definition (see Section 3) agrees with the present one. Example 1. , p) is a a-finite measure space and 1 5 p < 00, then the Riesz representation theorem shows that the dual of Lp(p)can be identified with Lq(p), where l / p l / q = 1 .
