We give explicit lower bounds on the modular degree of a rational elliptic curve. The technique is via a convolution-type formula involving the symmetric-square L-function, for which an analogue of “no Siegel zeros” is known due to a result of Goldfeld, Hoffstein, and Lieman; our main task...

The program ISO 1.0 was developed in computer algebra system GAP using programming language GAP. It is aimed for calculation of invariants of modular group algebras of finite p-groups and investigation of the modular isomorphism problem of group algebras. It allows to calculate and manage a...

In a century of complexity, organizations are moving towards open innovation. So, contemporary Innovation Management Systems have to deal with the distributed, heterogeneous and fast growing characteristics of knowledge that are available in different forms and are rather weakly structured. In...
