In this paper, we characterize the vanishing of such invariants for a curve given as a transversal union of plane curves ′ and ′′ in terms of the finiteness and the vanishing properties of the invariants of ′ and ′′, and whether or not they are irreducible. As a consequence, we prove that the multivariable Alexander polynomial Δmulti is a power of ( − 1), and we characterize when Δmulti = 1 in terms of the defining equations of ′ and ′′. Our results impose obstructions on the class of groups that can be realized as fundamental groups of complements of a transversal union of curves. 000124350 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E22-20R$$9info:eu-repo/grantAgreement/ES/MICINN/PID2020-114750GB-C31/AEI/10.13039/501100011033 000124350 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000124350 590__ $$a0.8$$b2023 000124350 592__ $$a0.625$$b2023 000124350 591__ $$aMATHEMATICS$$b179 / 490 = 0.365$$c2023$$dQ2$$eT2 000124350 593__ $$aMathematics (miscellaneous)$$c2023$$dQ2 000124350 594__ $$a1.5$$b2023 000124350 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000124350 700__ $$aElduque, Eva 000124350 7102_ $$12006$$2440$$aUniversidad de Zaragoza$$bDpto.
