Integrating Predictive Models into Two-Sided Recommendations: A Matching-Theoretic Approach

Kazuki Sekiya, Suguru Otani, Yuki Komatsu +2

Two-sided platforms must recommend users to users, where matches (termed \emph{dates} in this paper) require mutual interest and activity on both sides. Naive ranking by predicted…

Riemann-Hilbert correspondence for unit F-crystals on embeddable algebraic varieties

Sachio Ohkawa

For a separated scheme X of finite type over a perfect field k of characteristic p>0 which admits an immersion into a proper smooth scheme over the truncated Witt ring $W_{n}…

On log local Cartier transform of higher level in characteristic p

Sachio Ohkawa

In our previous paper, given an integral log smooth morphism X→S of fine log schemes of characteristic p>0, we studied the Azumaya nature of the sheaf of log differential op…

On logarithmic nonabelian Hodge theory of higher level in characteristic p

Sachio Ohkawa

Given a natural number m and a log smooth integral morphism X→S of fine log schemes of characteristic p>0 with a lifting of its Frobenius pull-back X′→S modulo $p^{2}…
