Dynamic Analysis of a Model for Spruce Budworm Populations with Delay by Ahmadjan Muhammadhaji, Azhar Halik

“…Compared with previous studies, both autonomous and nonautonomous delayed spruce budworm population models are considered. By using the inequality techniques, continuation theorem, and the construction of suitable Lyapunov functional, we establish a set of easily verifiable sufficient conditions on the permanence, existence, and global attractivity of positive periodic solutions for the considered system. …”

Sur certains invariants des algèbres artiniennes commutatives by Aleksandrov, Alexandre

“…For example, we show that the length of the module of Kähler differentials of any local artinian Gorenstein algebra over $\mathbb{C}$ is greater than or equal to the length of the algebra itself minus one. We then prove, employing the canonical duality in the cotangent complex, that if the corresponding thick point is smoothable, then its Tjurina and Milnor numbers satisfy the inequality $\tau \geqslant \mu $.…”
