    Mixed Identities for Oligomorphic Automorphism Groups
    with Manuel Bodirsky and Andreas Thom
    Journal of Symbolic Logic 1-23. forthcoming.
    We study mixed identities for oligomorphic automorphism groups of countable relational structures. Our main result gives sufficient conditions for such a group to not admit a mixed identity without particular constants. We study numerous examples and prove in many cases that there cannot be a non-singular mixed identity.

    The discussions on the eternity of the world in the academic circles of the 13th c. are not dealing with the real issue. They are pointing out what philosophy and theology each can effect, and their relation to each other. Gradually the autonomy of philosophy will emerge as a result of these discussions

    Resumo: No capítulo 5 do Livro III De anima (430a10-19) Aristóteles distingue entre o νοῦς ποιητικός (nous poietikós), chamado pelos Latinos intellectus agens (intelecto agente), e νοῦς παθητικός (nous pathetikós), chamado pelos Latinos intellectus passivus, ou seja, intellectus possibilis (intelecto possível), termos técnicos e filosóficos mais comuns.
