K9Y3[Si12O32]F2
Single-crystals of the title compound, nona-potassium triyttrium dodeca-silicate difluoride, were obtained from flux synthesis experiments in the system SiO2-Y2O3-KF. The crystal structure belongs to the group of single-layer silicates and is based on silicate sheets parallel to (110). A single layer contains secondary (Q (2)) and tertiary (Q (3)) silicate tetra-hedra in the ratio 1:2 and is bu...
متن کاملF2 Lanczos revisited
We present a new variant of the block Lanczos algorithm for finding vectors in the kernel of a symmetric matrix over F2. Our algorithm is at least as efficient as that of Peter Montgomery [6], while the sequence of matrices Wi constructed here have different algebraic properties that may be useful in eventually providing a provable upper bound on the time required to solve this problem. Namely,...
متن کاملPolynomial factorization over F2
We describe algorithms for polynomial factorization over the binary field F2, and their implementation. They allow polynomials of degree up to 250 000 to be factored in about one day of CPU time, distributing the work on two processors.
متن کاملFast matrix decomposition in F2
In this work an efficient algorithm to perform a block decomposition for large dense rectangular matrices with entries in 2 is presented. Matrices are stored as column blocks of row major matrices in order to facilitate rows operation and matrix multiplications with block of columns. One of the major bottlenecks of matrix decomposition is the pivoting involving both rows and column exchanges. S...
متن کاملOdd perfect polynomials over F2
A perfect polynomial over F2 is a polynomial A ∈ F2[x] that equals the sum of all its divisors. If gcd(A, x + x) = 1 then we say that A is odd. In this paper we show the non-existence of odd perfect polynomials with either three prime divisors or with at most nine prime divisors provided that all exponents are equal to 2.
