Second order differential invariants of linear frames
The aim of this paper is to characterize all second order tensor-valued and scalar differential invariants of the bundle of linear frames FX over an n-dimensional manifold X. These differential invariants are obtained by fa...

Rank 1 convex hulls of rotationally invariant functions
A rotationally invariant function $ f $ defined on the set $/mathbb {M}{n/times n} $ of all real square matrices of order $n$ has a representation $/tilde f$ on $/mathbb {R} n$ through the signed singular values of the matr...

Monotonicity of rotationally invariant convex and rank 1 convex functions.
Let f be a function on the space Lin of n by n matrices that is invariant with respect to the left and right multiplication by proper orthogonal tensors. It is shown fromLin satisfy certain ordering inequalities. The same h...

HIGHER-ORDER COMPACT EMBEDDINGS OF FUNCTION SPACES ON CARNOT-CARATHEODORY SPACES
A sufficient condition for higher-order compact embeddings on bounded domains in Carnot-Caratheodory spaces is established for the class of rearrangement-invariant function spaces. The condition is expressed in terms of com...

Higher-order Sobolev embeddings and isoperimetric inequalities
Optimal higher-order Sobolev type embeddings are shown to follow via isoperimetric inequalities. This establishes a higher-order analogue of a well-known link between first-order Sobolev embeddings and isoperimetric inequal...
