Molecular Aspects of Symmetry

The contents of this e-book were used in classes given by way of the writer. the 1st used to be a one-semester path for seniors on the collage of British Columbia; it used to be transparent that strong undergraduates have been completely in a position to dealing with straightforward team idea and its program to easy quantum chemical difficulties.

Let us focus on the two structures: Sources of Symmetry 47 (28) a.

Since I see no . . compelling evidence to the contrary,'' Kayne writes, ``I conclude that the LCA does underlie the entire set of syntactic representations and therefore that every syntactic representation is automatically associated with a ®xed linear ordering of its terminal symbols'' (1994, 49). In other words, Kayne considers the LCA as a pervasive condition on syntactic representations, which is so far indirectly motivated. Whether or not this view is empirically adequate is the topic of the next section and will constitute the central issue of this work.

Instead, I will approach the issue in a di¨erent way, by taking two conceptually di¨erent paths: on the one hand, I will argue against the current theory of movement based on checking of uninterpretable features; on the other, I will indicate the general design of grammar that Dynamic Antisymmetry points to, on the basis of selected empirical cases. 1 The Typology of Symmetry From a categorial point of view, we expect there to be only two types of points of symmetry: between two maximal projections (XP) or between two heads (X 0 ).
