Let X be a real linear space,P a family of separated seminorms on X and TP the locally convex separated topology on X generated by P.The concepts of the S-simplest form of a seminorm family P and the P-reflexive locally convex space (X,TP) are introduced.
The effects of iron substitution on the crystal structure and magnetic properties of SmCo6.8-xFexHf0.2 (x=0.1, 0.3, 0.5, and 0.7) compounds were investigated by means of X-ray powder diffraction and magnetic measurements.
Many research results are achieved as mentioned below. After the process of preparing bulk amorphous alloy by arc melting copper molding process is improved, bulk amorphous alloy (Zr41.2Ti13.8Cu12.5Ni10Be22.5) samples sized of 020X90 mm are prepared by using graphite crucible.
In this paper, we study the structure, magnetic properties and hyperfine interactions of Sr2FexMo2-xO6(1.0<x<1.5) and LiFePO4 compounds by using X-ray diffraction, magnetic measurement and Mossbauer spetroscopy.
An algebraicG-varietyX is called "wonderful", if the following conditions are satisfied:X is (connected) smooth and complete;X containsr irreducible smoothG-invariant divisors having a non void transversal intersection;G has 2r orbits inX.
We consider 3-parametric polynomialsPμ*(x; q, t, s) which replace theAn-series interpolation Macdonald polynomialsPμ*(x; q, t) for theBCn-type root system.
Ass → ∞ the polynomialsPμ*(x; q, t, s) becomePμ*(x; q, t).
LetG be a complex reductive Lie group with maximal compact subgroupK andG×X →X a holomorphic action on a Stein manifoldX.
Then there is a globalK-equivariant diffeomorphism φ:X→X with φ(R0)=R1.
