Copower Objects and Their Applications to Finiteness in Topoi
In this paper, we examine a new approach to topos theory – rather than considering subobjects, look at quotients. This leads to the notion of a copower object, which is the object of quotients of a given object. We study some properties of copower objects, many of which are similar to the properties of a power objects. Given enough categorical structure (i.e. in a pretopos) it is possible to ge...
متن کاملRemembering Another Aspect of Forgetting
Although forgetting is most often thought of in terms of declines in performance (response loss or impairment), another class of memory phenomena, the forgetting of stimulus attributes, has begun to attract experimental attention. In non-human animals, the loss of memory for stimulus features is reflected in the flattening of stimulus generalization gradients as well as in the attenuation of th...
متن کاملAnother Aspect of the Pair - List Reading in Japanese
1 The glosses used in this paper are as follows: Nom = nominative Case, Acc = Accusative Case, Dat = dative Case, Q = Question particle, Cop = copula, Top = topic marker, Nmlz = nominalizer. 2 Unlike English sluicing which is generally considered as TP deletion following overt wh-movement, as in (i), Japanese sluicing-like construction is considered as the deletion of the presupposition part of...
متن کاملSheaf representation for topoi
It is shown that every (small) topos is equivalent to the category of global sections of a sheaf of so-called hyperlocal topoi, improving on a result of Lambek & Moerdijk. It follows that every boolean topos is equivalent to the global sections of a sheaf of well-pointed topoi. Completeness theorems for higher-order logic result as corollaries. The main result of this paper is the following. Th...
متن کاملAnother aspect-oriented approach to diagnosis of cardiac amyloidosis.
We read with interest the article by Esterbrook et al on cardiac amyloidosis. Authors demonstrated very excellent clinical presentation and a challenging diagnostic work-up in a patient with cardiac amyloidosis presenting with cough and breathlessness. However, we would like to discuss on another possible straightforward diagnostic approach for this case. A combination of poor R progression on ...
