Any document Let r and O be polar coordinates for R " , 0 r < 0,0 eS " -1 ( the unit sphere in R " ) . A domain D in R " is a starlike domain ( with respect to the origin ) if there exists a function B : S " -1 → R , � continuous and strictly positive , so that D = { re : 0 sr�... Let ( r , oi , oz ) , O S rSR , 0 S� 51,0 5 oz < 27 , be polar coordinates in Gr . Let the function x = x ( r , , �2 ) be the transformation from the polar coordinate to the orthogonal coordinate . We put f . ( r , 01 , 02 , t ) = f ( x ( r , 01 , 2 ) , t ) and set f ' ( ro�... POLAR SETS OF SOME GAUSSIAN PROCESSES by MICHEL (JEBER. 1. INTRODUCTION . Let S be a bounded set of R", N=1, and consider X (., s) a centered gaussian process defined on S. Je associate to it the process (1) X* = ( X1, X2,�... Śl Polar Morse–Smale vector fields Let X G *(M), r = 1, be a polar Morse–Smale vector field. ... cycle of X. If M is a k—torus and X is a polar Morse–Smale vector field on M then X has 2k stable cycles which intersect each other at the source. The representation theorem 3 allows to prove the following invariance properties ( propositions 17 and 18 ) . PROPOSITION 17 . Let 21 22 be open subsets of so and F a compact subset of z , N zz Then F is polar in 21 if and only if it is polar in�... Contributing further to the polar gradient of the bioelectric field may be the fact that conductivity is much greater up and down the stem than across the stem ( HOPE and ROBERTSON 1953), and such conductivity might limit lateral transport�... Let g : C” – C and h: C” – C be polar weighted homogeneous polynomials. Consider the polynomial on C" X (C" defined by f(z,w) = g(z) –– h(w), which is also a polar weighted homogeneous polynomial (Example 2.6). Let x = f_1(1) C C” x C",�... The polar SFE component has same trend with total SFE , but the dispersive SFE component is on the contrary exactly . The polar SFE component is also lower than the dispersive SFE component . This is resulting from hydrogen bonding�... Jacques Azema, Michel Emery, Marc Yor.
