Second Order Differential Operators on the Configuration Spaces

Γ = { γ ⊂ R ∣∣ |γΛ| < +∞ for any compact Λ ⊂ Rd}, where | · | means the cardinality of a set and γΛ = γ ∩ Λ. Let us define the σ-algebra B (Γ) as the minimal σ-algebra such that all mappings Γ γ −→ |γΛ| are B(Γ)-measurable for any Λ ∈ Bc(R), where Bc(R) is the family of all Borel subsets of Rd with compact closure. The space Γ can be naturally embedded into the space M(Rd) of all measures on Rd...

On high order finite element spaces of differential forms

We show how the high order finite element spaces of differential forms due to Raviart-Thomas-Nédelec-Hiptmair fit into the framework of finite element systems, in an elaboration of the finite element exterior calculus of Arnold-Falk-Winther. Based on observations by Bossavit, we provide new low order degrees of freedom. As an alternative to existing choices of bases, we provide canonical resolu...

Actions of Join Spaces of Continuous Functions on Hypergroups of Second-Order Linear Differential Operators

One from classical constructions of algebraic binary hyperstructures (semihypergroups and hypergroups) from ordered algebraic systems is based on a certain Lemma on principal ends generated by products of pairs of elements – shortly termed as Ends-Lemma. First version of this auxiliary lemma was obtained in the monography [3]. The mentioned lemma is applied not only in case of hyperstructures c...

A RESEARCH NOTE ON THE SECOND ORDER DIFFERENTIAL EQUATION

Let U(t, ) be solution of the Dirichlet problem y''+( t-q(t))y= 0 - 1 t l y(-l)= 0 = y(x), with variabIe t on (-1, x), for fixed x, which satisfies the initial condition U(-1, )=0 , (-1, )=1. In this paper, the asymptotic representation of the corresponding eigenfunctions of the eigen values has been investigated . Furthermore, the leading term of the asymptotic formula for ...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
