Classificació dels subgrups finits de GL2(C)
"Es tracta de fer la classificació de tots els subgrups finits del grup lineal 2-dimensional complex. Les eines necessàries són la teoria de grups bàsica, la teoria de les representacions de grups, i la classificació cohomològica de les extensions de ...

Finite element formulation of the finite rotation solid element
Finite Elements in Analysis and Design, 1995The paper describes the development of an 8-node solid finite element capable of undergoing both large displacements and large rotations. The constitutive law chosen is for an elastic material. The element is developed on a sound variational basis. The incompatible modes are employed to produce a ‘ locking’ free performance.

Proceedings of IEEE-SP International Symposium on Time- Frequency and Time-Scale Analysis, 1995
Finite elements with support on two intervals span the space of piecewise polynomials with degree 2n-1 and n-1 continuous derivatives. Function values and n-1 derivatives at each mesh-point determine these "Hermite finite elements". The n basis functions satisfy a dilation equation with n by n matrix coefficients. Orthogonal to this scaling subspace is

Probabilistic finite element analysis of a craniofacial finite element model
Journal of Theoretical Biology, 2012We employed a probabilistic finite element analysis (FEA) method to determine how variability in material property values affects stress and strain values in a finite model of a Macaca fascicularis cranium. The material behavior of cortical bone varied in three ways: isotropic homogeneous, isotropic non-homogeneous, and orthotropic non-homogeneous. The

Preconditioning Complicated Finite Elements by Simple Finite Elements
SIAM Journal on Scientific Computing, 1996A very subtle and useful method of preconditioning finite elements with a large number of degrees of freedom by simpler finite elements is proposed. A second-order problem (Laplace equation) and a fourth-order problem (biharmonic equation) are considered as examples.

SIAM Journal on Numerical Analysis, 1972
This paper considers matrices arising from the use of finite element techniques in least-squares approximation and in elliptic partial differential equations; it studies their properties of numerical stability, and in particular, it establishes bounds for their inverses with respect to the uniform norm.
