Generalized Kummer congruences and $p$-adic families of motives Alexei A. Panchishkin 1995-030 We describe some new general constructions of $p$-adic $L$-functions attached to certain arithmetically defined complex $L$-functions coming from motives over $\Q$ with coefficiens in a number field $T$, $[T:\Q]<\infty$. These constructions are equivalent to proving some generalized Kummer congruences for critical special values of these complex $L$-functions.
