Hypoellipticity and loss of derivatives with Appendix Analyticity and loss of derivatives [PDF]

open access: yesAnnals of Mathematics vol. 162 no. 2, September 2005, pp. 943-986, 2006
For each value of k, two complex vector fields satisfying the bracket condition are exhibited the sum of whose squares is hypoelliptic but not subelliptic - in fact the operator loses k-1 derivatives in Sobolev norms. In the Appendix it is proven that this operator is analytic hypoelliptic.

Degenerate Perverse Sheaves on Abelian Varieties [PDF]

open access: yesarXiv, 2012
We analyze irreducible perverse sheaves on abelian varieties, defined over the complex numbers or the algebraic closure of a finite field, whose Euler characteristic is zero. We give a description of such perverse sheaves under assumptions for the case of simple abelian varieties.

Appendix A: Adequacy of representations of finite groups of Lie type [PDF]

open access: yesarXiv, 2012
Thorne introduced the notion of adequate representations as a weakening of the big representations used by Wiles and Taylor and others. In this appendix to Dieulefait's paper, Automorphy of Symm5(GL(2)) and base change, we show that certain representations of SL(2,q) are adequate.

Amyand’s Hernia in Adults – an Analysis of Recent Literature [PDF]

open access: yes
Amyand’s hernia is a rare disorder characterized by the presence of the vermiform appendix within an inguinal hernia. It is predominantly found in the pediatric age group, and its occurrence in adulthood is rare.

FGFR2 amplification in colorectal adenocarcinoma [PDF]

open access: yes, 2017
FGFR2 is recurrently amplified in 5% of gastric cancers and 1%–4% of breast cancers; however, this molecular alteration has never been reported in a primary colorectal cancer specimen.

CORN: Correlation-Driven Nonparametric Learning Approach for Portfolio Selection -- an Online Appendix [PDF]

open access: yesarXiv, 2013
This appendix proves CORN's universal consistency. One of Bin's PhD thesis examiner (Special thanks to Vladimir Vovk from Royal Holloway, University of London) suggested that CORN is universal and provided sketch proof of Lemma 1.6, which is the key of this proof. Based on the proof in Gy\"prfi et al. [2006], we thus prove CORN's universal consistency.
