n.
One of two or more atoms having the same atomic number but different mass numbers.

[iso- + Greek topos, place (so called because the isotopes of a chemical element occupy the same position in the periodic table of elements).]

(ˈaɪ səˌtoʊp)

n.
one of two or more forms of a chemical element having the same number of protons, or the same atomic number, but having different numbers of neutrons, or different atomic weights.

i·so·tope

(ī′sə-tōp′)
One of two or more atoms that have the same number of protons but a different number of neutrons. Carbon 12, the most common form of carbon, has six protons and six neutrons, whereas carbon 13 has six protons and seven neutrons.

Steinkamp points out the usefulness of the term isotopy for understanding the mechanics of polyvalence in Trakl's poetic language, where an isotopy is defined as a sphere of meaning within a text produced by the repetition of a basic meaning trait or seme (22526).
Different aspects of physicality, and especially of sexuality, told from a girl's or women's perspective create a strong thematic and motivic isotopy for the whole.
n] enjoy a kind of "Lagrangian calibration" and are therefore extremizers of the volume in their Lagrangian isotopy class (but not in their whole isotopy class).
Entitling the first part (set of poems and narrative fragments analysis) de De l'Imperfection, the term "fracture" stands for aesthetic accident, constituting a isotopy rapture, a "momentary lightning in everyday life" (GREIMAS, 2002, p.
Topological spinning of F is to add an annulus winding around a torus or Klein bottle boundary component to F and compute the isotopy class of the resulting surface keeping its boundary fixed.
The treatise defines the combinatorial Floer homology of a transverse pair of non-contractible non-isotopic embedded loops in an oriented 2-manifold without boundary, proves that it is invariant under isotopy, and proves that it is isomorphic to the original Lagrangian Floer homology.
By the planar isotopy we mean the motion of the projection in the plane that preserves the graphical structure of the underlyinguniverse.
It covers elements of the basic theory of anisotropic wave propagation, the influence of anisotropy on point-source radiation and amplitude variation with offset (AVO) analysis, normal-movement velocity in layered anisotropic media, nonhyperbolic reflection moveout, reflection moveout of mode-converted waves, P-wave time-domain signatures in transversely isotopic media, velocity analysis and parameter estimation for vertical transverse isotopy (VTI) media, and P-wave imaging for VTI media.
