ON A BOUNDARY-VALUE PROBLEM FOR THE THIRD ORDER OF A PARABOLO-HYPERBOLIC TYPE IN A VAGINATED SIXTY-DIMENSIONAL REGION [PDF]

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2016
In the study of problems of mathematical physics, the methods of differential and integral equations are used. This paper is an example of the application of these methods to the solution of a single boundary-value problem for a third-order parabolic ...

Spherical Rectangles [PDF]

open access: yesArnold Mathematical Journal, 2016
We study spherical quadrilaterals whose angles are odd multiples of pi/2, and the equivalent accessory parameter problem for the Heun equation. We obtain a classification of these quadrilaterals up to isometry. For given angles, there are finitely many one-dimensional continuous families which we enumerate.

The Rectangle Attack — Rectangling the Serpent [PDF]

open access: yes, 2001
Serpent is one of the 5 AES finalists. The best attack published so far analyzes up to 9 rounds. In this paper we present attacks on 7-round, 8-round, and 10-round variants of Serpent. We attack a 7- round variant with all key lengths, and 8- and 10-round variants with 256-bit keys. The 10-round attack on the 256-bit keys variants is the best published
