Cartesian currents in the calculus of variations

This monograph (in volumes) bargains with non scalar variational difficulties coming up in geometry, as harmonic mappings among Riemannian manifolds and minimum graphs, and in physics, as solid equilibrium configuations in nonlinear elasticity or for liquid crystals. The presentation is selfcontained and obtainable to non experts.

Partially ordered rings and semi-algebraic geometry

The aim of this designated ebook is to set up merely algebraic foundations for the advance of yes elements of topology. a few topologists search to appreciate geometric homes of options to finite platforms of equations or inequalities and configurations which in a few feel truly ensue within the actual international.

Advances in Robot Kinematics and Computational Geometry

Lately, examine in robotic kinematics has attracted researchers with diverse theoretical profiles and backgrounds, corresponding to mechanical and electrica! engineering, computing device technological know-how, and arithmetic. It comprises themes and difficulties which are regular for this region and can't simply be met in other places. for that reason, a specialized clinical group has built concentrating its curiosity in a wide category of difficulties during this zone and representing a conglomeration of disciplines together with mechanics, idea of platforms, algebra, and others.

C) is a consequence of b) and the standard regularity theorem of linear elliptic partial differential equations. The last half of b) follows from Proposition 1. Let h be a ranic r Hermitian matrix valued function defined on an n-dimensional Kahler manifold (Y, u) which belongs to H1 Assume that h and hr1 are uniformly bounded and it satisfies A^a/i/i" 1 ) = / (1) in a weak sense with a uniformly bounded function f, then h belongs to C}'a for anyO < a < 1 and admits an estimate depending only on ||/i||£,°°, | | ^ _ 1 | U ~ , | | / | | L ° ° and the geometry of (Y, UJ).

Then ((VwwQ)(H,K)x,x) {(V n)(H,K)X,x)-- =--(T»(H,0(K,W)),X) (TH(H,6(K,W)),X) In particular, forallWeV eH. for all W € V and H, H, K Ken. ((vwn)(H,x)x,x) = o for all W £ V and H € H. Proof: Since we are interested only in the horizontal part, we may replace fi by QH = Q% ® dz13 ® 6a. Since Vw dz0 = 0 and V - ^ 6 a = 0, we have Vwn" = (VWQ%) 9 dz0 ® Sa.
