Pseudo-Hadamard matrices of the first generation and an algorithm for producing them
Ruslan Sharipov
Hadamard matrices in presentation are square matrices whose entries are zeros and ones and whose rows considered as vectors in produce the Gram mat…
Hadamard matrices in presentation and an algorithm for generating them
Ruslan Sharipov
Hadamard matrices are square matrices whose entries are ones and minus ones and whose rows are orthogonal to each other with respect to the standard scalar product in $…
On a simplified version of Hadamard's maximal determinant problem
Ruslan Sharipov
Hadamard's maximal determinant problem consists in finding the maximal value of the determinant of a square matrix whose entries are plus or minus ones. This is a diffi…
On cylindrical regression in three-dimensional Euclidean space
O. V. Ageev, R. A. Sharipov
The three-dimensional cylindrical regression problem is a problem of finding a cylinder best fitting a group of points in three-dimensional Euclidean space. The words best fitting…
On linear regression in three-dimensional Euclidean space
O. V. Ageev, R. A. Sharipov
The three-dimensional linear regression problem is a problem of finding a spacial straight line best fitting a group of points in three-dimensional Euclidean space. This problem is…
On simultaneous approximation of several eigenvalues of a semi-definite self-adjoint linear operator in a Hilbert space
Ruslan Sharipov
A lower semi-definite self-adjoint linear operator in a Hilbert space is taken whose discrete spectrum is not empty and comprises at least several eigenvalues $λ_{min}=λ_1\leqslant…
