DOI: 10.1016/j.ajmsc.2019.10.002
Abstract: Let E be an elliptic curve with Weierstrass form y2=x3−px, where p is a prime number and let E[m] be its m-torsion subgroup. Let p1=(x1,y1) and p2=(x2,y2) be a basis for E[m], then we prove… read more here.

DOI: 10.1108/ajms-10-2020-0097
Abstract: PurposeThe author considers an invariant lightlike submanifold M, whose transversal bundle tr(TM) is flat, in an indefinite Sasakian manifold M¯(c) of constant φ¯-sectional curvature c. Under some geometric conditions, the author demonstrates that c=1, that… read more here.

DOI: 10.1515/acv-2019-0004
Abstract: We study planar N-bubbles that minimize, under an area constraint, a weighted perimeter P ε {P_{\varepsilon}} depending on a small parameter ε > 0 {\varepsilon>0} . Specifically, we weight 2 - ε {2-\varepsilon} the boundary… read more here.
